It depends on the audience, I suspect. There is a strong requirement
for testability of techniques from authoring tool, evaluation and
repair tool and user agent developers, who are primary audiences of
the techniques. Also, by having multiple presentations of the material
we can create views of the techniques in which only some of the
information (namely, that relevant to a particular audience or for a
specific purpose) is included. Does this adequately address the
concern? If not, what alternatives are there?

Agreed. A concise exposition is always to be preferred.

I suspect you missed the main point, which is that where one
technology operates within a host language, the techniques for the
dependent technology, CSS for example, should be included with the
techniques for the host language rather than as a separate document.
The second point in the above passage is as you stated it, however.
While it is true that CSS works with XML, HTML was here mentioned only
as an example rather than in an effort to be exhaustive.
