Functions, operators, and data types for XPath 3.0
fn:serialize() function: the implementation has been changed to match the
2011 version of the W3C specification. This changes the format of the serialization
parameters supplied in the second argument to the function.
outermost() are implemented.
parse-xml-fragment() is implemented.
format-date() and friends, timezone formatting has been updated to match the
current spec. This may create incompatible changes. The changes apply whether or not
XPath 3.0 processing is enabled.
The implementation of
deep-equal() has been changed to enforce the rule that
the type annotations of two element nodes must have the same variety. This corrects
a long-standing non-conformance, but may cause incompatibility, especially when comparing
a schema-validated document against an unvalidated document. A new flag "v" has been added
to the Saxon equivalent function
saxon:deep-equal() to suppress this check.
