Agreed and this is something I've contemplated and will start implementing
this at some point if no one beats me to it.

Using the custom tags you won't need any 'escape tag', we'll just pluck out
our custom tags for inclusion in the documentation.

XDoclet doesn't use <javadoc> (the builtin Ant task), it uses its own custom
Ant task.  There are actually a few custom Ant tasks in the XDoclet API.

I forwarded your message on over to the head XDoclet guy and the stuff in
quotes is from him:

"That's what we do but I guess he meant not using javadoc at all. That's
not possible, yet. We have to launch javadoc, and javadoc loads all
classes and parses them, creates a tree of class descriptions and then
we start working on it. We're working on our doclet api which will
replace sun's doclet api. Hopefully we can optimize it because xdoclet
does not need all the features sun's doclet api provides, and we can
make it in-process. Just wait a little more...." [There is a codebase
already in progress called xjavadoc, under the XDoclet's CVS]

"We do it. But it's done after javadoc load classes. I'll try to find a
way to do it before javadoc runs :o)

OK, I'll make it my priority number one :o)
You just go on and I'll make it faster."

Once I start digging into this with the Ant 1.x documentation, I'll work on
the XDoclet codebase to add optimizations if they haven't gotten to it

Maybe we could speed it up by using <uptodate>?  This would probably mean
separating out the filesets it operates on for each XML file it generates,
but this might not work too well if the entire codebase has to be inspected
for each XML file.

And perhaps you could work with the XDoclet team to be sure myrmidon really
handles their needs nicely!  :)
