Two requests for the XML plug-in of jedit:

1) A fix for the issue mentioned in the post "same problem with XSL stylesheets" of this thread: "http://community.jedit.org/?q=node/view/1262/". Basically, JEdit doesn't look at the namespaces defined within a tag when judging whether a tag has a valid namespace, so if you have:

<xsp:page xmlns:xsp="http://apache.org/xsp">

you get the error:

"test.xml:4:cvc-elt.1: Cannot find the declaration of element 'xsp:page'."

even though the XML standards say that this is a perfectly acceptable way to declare a namespace.

2) Support for RELAX NG (the OASIS standard) schemas. Even better would be support for Sun-style RELAX NG with embedded Schematron schemas (http://www.sun.com/software/xml/developers/schematronaddon/), but I imagine this would be more trouble to add than it would be worth. Since basic RELAX NG is a very wide-spread standard however, it should be relatively easy to find a validator for it and integrate it with the existing XML plug-in for jedit.
