I apologize if this has been discussed already or is not pertinent to this
discussion - I may be way out of scope for these guidelines.  However, I am
curious how server-side scripting directives or other types of
place-holding elements that are not defined anywhere fit into the picture?  

For example, the WAI guidelines are all generated from "source" documents.
These documents are primarily HTML but also include directives for where to
pull information into the document at the time of generation.  For example,
there is a statement that says, "put a table of contents here" another that
says "put the references here."  However, I like to edit chunks of content
in a WYSIWYG editor and luckily, all of the directives are commented out
(e.g., <!-- processing directive -->) so this isn't an issue - for our set
of documents.  

These strategies won't be found in a DTD nor in a registry anywhere (I
assume).  This will further the problem that Jutta outlines, because there
is a slim chance at best that the tool could a. access the server-side
script then b. analyze the content it produces for accessibility.

I don't think we can assume that people using these types of templates are
versed in a markup language. A company could provide a template to all
employees regardless of markup language knowledge and say, "put your
content here. we'll generate the rest (nav bars, advertising, etc.)."

Perhaps this isn't an issue at all - if all directives are commented out
the tool will ignore them. but, i'm not sure that is a safe assumption,
either (unless it becomes an authoring practice....i can add something to
techniques for server-side scripting in the WCAG but that doesn't guarantee
