Mukul Gandhi commented on XERCESJ-1573:
---------------------------------------
My guess is, that every usage of XSD 1.1 assertions may not result in same
performance problem that you've reported. Perhaps the performance problem that
you've reported, is related to specific class of XPath expressions (for e.g,
that build date objects or do date arithmetic) -- perhaps you can help us
identify these things.
As a second check, you may do for e.g same performance tests with following XSD
type definitions,
<!-- tests if a number is even -->
<xs:simpleType name="evenNumber">
<xs:restriction base="xs:integer">
<xs:assert test="$value mod 2 = 0"/>
</xs:restriction>
</xs:simpleType>
<!-- enforce cardinality of a sequence via an assertion -->
<xs:complexType>
<xs:sequence>
<xs:element name="a" type="xs:string" maxOccurs="unbounded"/>
</xs:sequence>
<xs:assert test="count(a) = 5"/>
</xs:complexType>
and report to us the results.
