TimBL didn't need to say anything for me to believe there was an
institutional animus at the W3C against processing instructions. 

I've been told a number of times that this was the 'final W3C word' on
processing instructions, though phrased rather politely:


The use of XML processing instructions in this specification should not
be taken as a precedent. The W3C does not anticipate recommending the
use of processing instructions in any future specification. The
Rationale explains why they were used in this specification.

Along with the excuse for using them IN THIS CASE:

There was an urgent requirement for a specification for style sheet
linking that could be completed in time for the next release from major
browser vendors. Only by choosing a simple mechanism closely based on a
proven existing mechanism could the specification be completed in time
to meet this requirement.

Use of a processing instruction avoids polluting the main document
structure with application specific processing information.

The mechanism chosen for this version of the specification is not a
constraint on the additional mechanisms planned for future versions.
There is no expectation that these will use processing instructions;
indeed they may not include the linking information in the source

The animus has also been noted quite regularly on xml-dev.
