Unfortunately it's not about validating but about producing parsable DocBook. Since the Dsssl stylesheets from N Walsh and the DocBook XSL stylesheets seem to be standard, we will have to follow this defacto standard. > don't try to reinvent the wheel.

What about the following transformation scheme: : to .. .. to -.. _ to -- -- to -.-- -. to -.-. - to - . to . other to -.code eg. "sec:what-a-.0_mess--!" to "sec..what-a-.-.0--mess-.---.33" Looks like Morse, eh? But "sec:a_new_idea-1" just becomes "sec..a--new--idea-1" which should be ok. Oh yes, and "52-degree" becomes "x52-degree". Note that citations are not coded as ID so they can stay as they are. Just labels and references. /Andreas P.S. Chris, if you write lines longer than 78 chars it is a PITA to quote you with gmane. And I like gmane because it is possible to make true followups, not just use the same subject.
