Hi Michael,
Thanks for the feedback. A complicating factor in our
requirements is that (unlike your <note> tag [see
your message below] which, when present, always
comes as the second of a pair of tags), our tag for
<location-specific_Comment> can appear *anywhere* in
the character data. [Basically, we are marking up
transcriptions of medieval manuscripts, where the
manuscript content is character data, and editorial
comments are treated as markup.] The content of our
<target_Type> must, I think, be "mixed".

JT suggested leaving the Pattern out of our Schema
declarations, and enforcing our RegEx via a separate
validation-step. I expect she is thinking this could
be triggered by an <xs:appinfo> tag, or somehow by
pipelining the Schema-validator with another program.
Such a program would need to enforce the RegEx on
character data within <target_Type> and ignore any
<location-specific_Comment> tags.

By our requirements, it is crucial that the character
data beween the <target_Type> tags *must* be RegEx-
valid. I'm unsure how we could implement pipelining
in an automated way, except at the data-entry side.
Our instance docs are intended to be "first-class
objects" on the Web, and I see no way currently to
invoke a proprietary second-step validator during
the course of browser retrieval of an XML doc. Any
suggestions -- from anyone -- would be most welcome.
Cheers,
- Wyatt
