Knut Anders Hatlen commented on DERBY-6633:
-------------------------------------------
The requirement is mentioned in the "XML data types and operators" topic of the
developer's guide. I believe we can replace the paragraph that begins with "For
the XML operators to work properly", with one that simply states that the JVM
needs to have a working implementation of
javax.xml.parsers.DocumentBuilderFactory and javax.xml.xpath.XPathFactory. (All
supported JVMs are supposed to have that, so it might be redundant, but I don't
see any harm in mentioning it.) The "Classpath and version issues" paragraph
can probably be removed now.
In the reference manual, there's a usage note in the topics for XMLEXISTS,
XMLPARSE, XMLQUERY and XMLSERIALIZE, as well as in the "XML limitations" topic.
I think we can either remove the usage note, or replace it with similar wording
as above (require working implementation of j.x.p.DocumentBuilderFactory and
j.x.x.XPathFactory).
