Broadened signatures and improved compliance for existing functions:
- fn:compare: broadened to anyAtomicType, numeric total order,
duration/datetime ordering per QT4 spec
- fn:deep-equal: text node merging across comments/PIs, options map
support, BigInteger overflow fix for fn:round
- fn:head/fn:tail: expanded to fn:foot/fn:trunk (XQ4 aliases)
- fn:max/fn:min: duration comparison support, decimal precision
- fn:doc/fn:doc-available: security-gated file:// URI resolution,
fn:doc#2 overload
- fn:unparsed-text: BOM stripping, fn:unparsed-text-lines fix
- fn:matches/fn:replace/fn:tokenize: regex enhancements
- fn:path#2: output format parameter
- fn:analyze-string: reflection proxy for Saxon compatibility
- fn:parse-json: option validation, empty sequence args, xs:integer
for JSON integers
- fn:load-xquery-module: content option (XQ4)
- fn:format-number: negative exponent zero-padding, map overload,
char:rendition pattern
- fn:format-date/fn:format-time: comprehensive improvements
- Collations: supplementary codepoint comparison
- RangeSequence: primitive long storage optimization
- Error codes: W3C alignment across casting and value types
- JSON serialization: XDM mode bypass fix, duplicate key detection
