Re: [Jersey] Tight integration into WADL 'doc' element

Hi Marc,

I see. I had in mind that there would be a new annotation (or param
on existing annotations) that let you document these elements, but I
can appreciate that Javadoc would be

1) more intuitive/less learning curve
2) more readable compared to an inline string.

Funny thing is, I just open-sourced a doclet that generates an XML
representation of the data in Javadoc on google code. I'm thinking one
could use XSLT/XPATH on the output of this doclet, and create the WADL
from it. Are there any red flags with using this XML-generating,
maven-based, Apache 2.0 licensed project hosted on google code to help
accomplish this? Or would there be a reason that this must be a new
doclet sourced directly with Jersey?

I don't have a good feel for the size of this task, but I am very
interested. I'd like to look through the Jersey source a little
tonight to get a better feel...

Thanks,
Seth
