I guess it's only the relative file-name case where it's necessary to
allow the file not to exist. Typically, this variable would contain
something like
("schemas.xml" "/home/jjc/schema/schemas.xml"
"/usr/share/schema/schemas.xml")
which means to use a "schemas.xml" file in the document's directory if
such a file exists, before the standard directories. Lots of the time
the document's directory won't have such a file, so you really don't
want an error in that case.

What's wrong with the syntax: "variable ... specifies the list"?

It's talking about the same thing as the first paragraph. I'll merge
the first two paragraphs.

I think the first one on the list, or maybe the first existing one.

The latter. I'll say so explicitly.

Yes.

I'll add one.

Yes. Everything always first come, first served. I'll emphasive that.

Like xsd:token. Strip leading and trailing whitespace; other strings of
whitespace normalized to a single character.

The pi target is "my-doctype", which is a name.

Hmm. I think it's enough to do applyFollowingRules for include, but
maybe an optional ruleType attribute on include would be useful.
Something to think about.
