Re: Implementing support for filterin/filterout in assemblies

Hi Peter,

I don't know of an existing implementation, but I would be willing to 
assist with your efforts.

Before you start, though, you might not need to use the filterin 
filterout elements if you just need simple conditional exclusion.  Note 
that assembly elements like module accept the regular DocBook 
effectivity attributes.  You can preprocess your assembly file 
containing those attributes using the stock profiling/profile.xsl 
stylesheet and command line parameters to produce a profiled assembly.as 
described here under the "Two-pass processing" heading.
