W3C XForms 1.1 Test Suite — Coverage Status

Source: https://www.w3.org/MarkUp/Forms/Test/XForms1.1/Edition1/

Engine Gaps

The following categories of W3C test failures reflect known limitations in the Saxon-Forms engine. These are tracked here to guide future development.

Recently resolved

The following gaps were resolved and are listed here for reference:

• Readonly MIP enforcement — readonly="true()" bind now propagates to HTML inputs, including inheritance from ancestor bindings. Resolved: 6.1.2.a, 6.1.2.b, 7.2.f.
• index() returns NaN — Non-existent repeat IDs now return NaN per XForms 1.1 §7.7.5. Resolved: 7.7.5.b; 4.7.c test updated.
• XPath 3.1 type coercion — Calculate/relevant expressions wrapped in try/catch to handle empty-string arithmetic crashes. Resolved: 6.1.5.a, 6.1.4.b.
• min()/max() negative tests — XForms-compliant wrappers return NaN instead of throwing XPath 3.1 type errors. Resolved: 7.7.2.b, 7.7.3.b.
• Constraint validation events — xforms-valid/xforms-invalid events now dispatch after setvalue changes constraint state. Resolved: 6.1.6.a.
• Switch/case selector issues — Test selectors scoped to .xforms-switch to avoid matching instruction text. Resolved: 9.1.1.a2, 9.1.1.b, 9.2.2.b, 9.2.2.c.
• Reset action — Initial instance snapshots saved on construction and restored on xf:reset. Resolved: 10.a.
• setfocus action — Enhanced setFocus JS with suffixed-ID fallback and group→first-child focus. Resolved: 9.1.1.c, 10.7.a.
• current() in repeat — Output @value starting with instance(...) no longer short-circuits $instanceField inside repeats, so current() resolves to the repeat item. Resolved: 7.10.2.b.
• position()/last() in bind calculate — Calculate expressions containing position() or last() now substitute actual nodeset position/size before evaluation. Resolved: 7.2.e.
• adjust-dateTime-to-timezone() test — Test updated with timezone-aware assertions instead of hardcoded Pacific time. Resolved: 7.9.8.a.
• Model-construction crash (no instance) — evaluate-xpath-with-context-node parameter $context-node made optional (node()?) so models without instances don’t crash the transform. Resolved: 4.2.1.a, 4.2.1.d, 4.2.2.a, 4.2.3.a, 4.5.2.a.
• Select/select1 non-incremental sequencing — Non-incremental <select>/<select1> onchange handling now performs inline recalculate/revalidate/refresh and avoids duplicate outer deferred-cycle dispatch from xforms-value-changed wrappers. Resolved: 4.6.3.a, 4.6.3.b, 4.6.3.c.
• Action context resolution for bind-based actions — Action-map persistence now keeps bind metadata and insert/delete now resolve local context first with absolute-ref fallback. Resolved: 10.4.b, 10.18.b.
• id() function routing and implementation — Added id to function rewriting and implemented xforms:id() overloads (supports fn:id, @xml:id, and xsi:type ID, including both W3C xsi namespace URIs). Resolved: 7.10.3.a, 7.10.3.b, 7.10.3.c.
• Chapter 2 submit selector alignment — Behavioral tests now match fixture submission IDs (submit for 2.1.a/2.2.a and submit01 for 2.3.a), clearing temporary selector regressions. Resolved: 2.1.a, 2.2.a, 2.3.a.
• Regression gate status — Latest W3C conformance gate run reports new_regressions_count: 0 and promoted baseline after the above fixes.

Insert/delete action semantics (13 tests)

Root causes vary across the cluster:

• Model-level xforms-ready handlers — Insert actions defined as direct children of <xforms:model> (without ev:observer) do not execute reliably. Affects Appendix B tests (B.1, B.3, B.4, B.13) which use <xforms:action ev:event="xforms-ready"><xforms:insert .../>.
• Multi-instance @context resolution — Sequential insert actions that switch between instances via @context (e.g., context="instance('second')" then context="number_list[2]") resolve against the wrong instance for later actions. Affects: 10.3.a, 10.3.c.
• @bind/@model on insert — Crashes the XSLT transform. Affects: 10.3.b.
• @at position evaluation — Insert/delete @at attribute position calculation produces wrong results for some trigger sequences. Affects: 10.3.d, 10.4.d.
• Delete index tracking — Post-delete repeat index not updated correctly. Affects: 10.4.e, 10.4.f.
• Insert @context with absent @nodeset — Guard added for empty $ref-qualified but deeper model event execution issues remain. Affects: 10.3.h, 10.3.j.

Toggle action scoping in repeats (1 test)

xf:toggle inside a repeat iteration toggles ALL iterations’ switches instead of just the current one. The toggle action’s $source-control scoping mechanism (lines 6018–6024 in saxon-xforms.xsl) exists but $source-control is not being passed through the event dispatch chain (applyActions → action-toggle) from the clicked button’s DOM element.

Affected: 9.3.1.f.

Toggle case-child precedence (1 test)

The <xforms:case> child element of <xforms:toggle> (which specifies the target case with optional @value attribute) is not parsed by the toggle action. The action map builder (line 932–933) stores case text content but does not handle @value attribute precedence. The <xforms:case> child may also be incorrectly matched by the case rendering template (line 1545).

Affected: 10.6.1.b.

Model-event message dispatch (10 tests)

xforms:message elements that listen for model-level events (xforms-rebuild, xforms-reset, xforms-recalculate, xforms-revalidate, xforms-help, xforms-hint) do not produce modal dialogs when the event fires. The event itself may dispatch correctly, but the xforms:message handler does not invoke alert() / modal output.

Affected tests: 10.13.a (reset), 10.8.1.a/b (rebuild), 8.1.8.a (DOMActivate message), 8.2.2.a–c (help), 8.2.3.a–c (hint).

Submission features (4 tests)

• submission/@bind — The bind attribute on xforms:submission is parsed but does not filter the submitted instance data to only the bound node. The entire instance is sent. Affected: 11.1.b.
• xforms-submit-serialize event — The submission-body property set by an xforms-submit-serialize handler is not honoured; the original instance data is submitted. Affected: 11.3.b.
• xforms:header/xforms:name/xforms:value — Custom HTTP headers defined via child elements of xforms:submission are not added to the outgoing request. Affected: 11.8.1.a, 11.8.2.a.

Processing model behavioral failures (3 tests)

• 4.2.2.b — xforms-model-construct-done setvalue handler does not clear instance data (“Mitsubishi” persists). Root cause: event handler execution during model construction does not update instance values.
• 4.2.2.c1 — Form control referencing instance not yet loaded; output hidden after xforms-ready. Root cause: lazy instance resolution timing.
• 4.4.1.a — xforms-insert event properties (inserted-nodes) not populated in event handler after clicking trigger.

Container control edge cases (1 test)

• xf:repeat startindex — startindex attribute is set in XSLT but output value="index('...')" evaluates before the repeat template runs (document order issue). Affected: 9.3.1.b.

Miscellaneous (4 tests)

• Cancelled event propagation — dispatch with cancelable="true" + ev:preventDefault does not prevent the default action. Affected: 10.8.f.
• Insert with @context precision — Insert action context attribute does not produce expected result in a specific pattern. Affected: 10.3.j.
• Appendix H.2 — Renders empty. Affected: h.2.
• digest() without crypto — 7.5.b uses digest() in a binding-exception test; when crypto bundle is not loaded, the form crashes instead of raising the exception.
