I can't find good documentation on how to write modern tag libraries without Java in JSPX?
Spring Roo provides lots of examples (and seems to be only project that uses tagx extensively).
I may make this another question but every time I want to not repeat myself in JSPX (DRY) I feel like have to sacrifice valuable time and go create a tag library because there are no inline macros.
I feel like I must be missing something in JSP/X.
I stumbled on your question searching for something different.
I wrote a post about it at http://stories.stefanocazzola.it/2012/07/placing-your-custom-tags-inside-jar.html
