XSLT 2.0 implementation
system-property('xsl:vendor') now returns the string "Saxonica". Previously it returned
a more complex string that also identified the product version; this information should now be obtained using the
XSLT 2.0 system properties such as
system-property('xsl:product-version'). Information on the values
returned for each system property is at XSLT 2.0 Conformance.
The handling of type errors in an
<xsl:if>, or an
<xsl:otherwise> branch, has been made less draconian. If the construct appears in a context
where it is not allowed to return an empty sequence, the type error is no longer reported statically, but is only
reported if the implicit else/otherwise branch is actually taken at run-time. The immediate motivation for this
change is that it enables stylesheets generated using Altova's products to be executed; it also appears to be a
more reasonable interpretation of the intent of the specification.
