[jdom-interest] question on namespaces

I didn't really mean text, that was poorly stated. 
I do want to treat them as elements, just not elements
that have to be interpreted as fpl commands, but elements
that simply need to be copied to the output. I did figure
this problem out however. The trick was to instruct the
node factory to create a certain class for all elements 
not in the fpl namespace, and that class would - when being
processed - simply write the element to the output and recurse
down the tree to output more or process fpl commands down that
part of the tree. I did realize that validation is pretty much out,
so I gave up on that idea.

Question, how do xml editors like XMLSPy validate XSLT stylesheets?
How can it allow for ANY type of content in say an <xsl:template>?

You're trying to treat all the elements that aren't in the fpl namespace as text? That's not legitimate XML - your <script> tag is an element, not text, whether you're using JDOM or any other mechanism. To make it be text, you need to wrap it in a CDATA section, or use &lt;script&gt;.

In general, DTDs and namespaces work very poorly together. It's possible to modify a DTD to work with namespaces, but only if you require that the particular prefix that you've used in your DTD is the one that's used in each document. That works, but it pretty much goes against the intent and the usefulness of namespaces. On the other hand schemas are namespace-aware, though they're newer and more complicated.

These issues are particularly related to JDOM itself. You can probably find info about all these types of things in articles on sites like xml.com.
