📝 Summary

Summary by CodeRabbit

  • Documentation
    • Documented document matching for formatting profiles, symbol filters, references, colors, and file-path mappings using file patterns, root elements, namespace URIs, DOCTYPE identifiers, and grammar URIs.
    • Explained that different criteria combine with AND, multiple values for one criterion combine with OR, and a matcher with no criteria never matches.
    • Added formatting profile examples and clarified that the first matching profile applies, with unspecified settings inherited from global formatting options.

The changes document document-matcher criteria and add matcher-based configuration for formatting profiles, symbol filters, references, colors, and file-path support.

Changes: Document Matcher Configuration

Layer / File(s) Summary
Matcher reference documentation
docs/DocumentMatcher.md, docs/Symbols.md
Documents matcher criteria, value-combination rules, glob behavior, grammar URI sources, and configuration examples. Makes the symbol-filter pattern optional and describes it as a file glob.
Formatting profile configuration
package.json, docs/Formatting.md
Adds xml.format.profiles with document-matching criteria, formatting overrides, inherited global values, and first-match precedence.
Matcher-enabled XML features
package.json, docs/Features/*
Adds document-matcher criteria to symbol filters, references, colors, and file-path mappings. Adds examples for namespace URI, root element, and DOCTYPE public ID matching.

Review comments at @docs/Features/XMLColorsFeatures.md:
- Around line 74-87: Update the Android color example and the shared matcher
example so their matching criterion agrees with the illustrated XML document. In
docs/Features/XMLColorsFeatures.md lines 74-87, use a file pattern or show a
document whose root declares the Android namespace; in docs/DocumentMatcher.md
lines 181-194, make the example use that same working criterion and document.

Review comments at @docs/Symbols.md:
- Line 56: Update the `pattern` entry in the filter documentation to mark it as
optional, matching the schema behavior that allows filters selected only by
Document Matcher criteria.

Review comments at @package.json:
- Line 667: Replace the invalid `forceExpandMultiline` value with
`force-expand-multiline` in each profile example: package.json lines 667-667,

Seems good on this end. I'd prefer to check over eclipse-lemminx/lemminx#1875 first, but if you really want this merged, then I think that's probably fine.
