[jira] [Commented] (DERBY-6633) Remove DOM level 3 XPath requirement from description of XML operators

["Knut Anders Hatlen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DERBY-6633?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14040666#comment-14040666 ] 

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).
