Thanks! I went for
 http://docbook.sourceforge.net/projects/xsl/doc/tools/profiling.html

The way I read this I can use multiple attributes to implement orthogonal
criteria like "target=internal|public" and "profile=reference|annotation|rfc",
and I can use multiple values each single element's attribute. Is it recommended
to use attr="val1;val2" or better to define a "val1and2"? E.g. profile="full"
would be equivalent to "reference;annotation;rfc" and include all. 

I take it that using
   attr=profile val=rfc

is preferable to extending the DocBook common attributes.

I would also guess that per-element attributes allow for different kinds of
filtering strategies. For example

<section target="internal">
<title>Something Public</title>
<para target="public">
  Some public content
</para>
</section>

can be considered
 a) an error - contained elements should not contradict the parent's settings
 b) an override - parent element defines a default, which can be overridden
      (won't work for the "public" rendering as the <section> is lost)
 c) a mistake in the design? Don't make them common attributes?

Any recommendations for this? I found
   CVS docbook/xsl/tools/profile/profile.xsl

anything other examples I should look at? I'd expect that creating
inconsistent attributes in the XML will create a broken profiled
intermediate (e.g. title missing, empty para etc.), which will be
detected in the second stage processing, so for user convenience it 
might be worth having consistency checking in the profiling stage?

This example is different from 

  Example 5-1. Adding MethodName with a Customization Layer
  http://www.oasis-open.org/docbook/documentation/reference/html/ch05.html#EX-ADDMETHODNAME

is it?
