Performance enhancement for build from DOM
------------------------------------------
Key: WSCOMMONS-361
URL: https://issues.apache.org/jira/browse/WSCOMMONS-361
Project: WS-Commons
Issue Type: Improvement
Components: XmlSchema
Reporter: Daniel Kulp
Attachments: xmlschema-361.patch
When building from a DOM, the builder creates a NodeNamespaceContext for each
element and each time, it goes up all parent elements iterating over all the
attributes. That's expensive.
Attaching a patch that changes the NodeNamespaceContext to store the contxt in
the user data. It can then combine the current elemets with the parents very
quickly.
Also, if the same DOM is used multiple times, it can be much faster as no
contexts need to be created.
Downside: requires DOM level 3, but XmlSchema already doesn't work if DOM level
isn't level 3. (WSCOMMONS-358)
