DataPower XSLT Processor has something "like" this.


The "Attachment Protocol" describes it for policy actions:
http://publib.boulder.ibm.com/infocenter/wsdatap/4mt/index.jsp?topic=%2Fcom.ibm.dp.xs.doc%2Fxmlfirewalldevelopersguide.xs40121.htm&resultof=%22attachment%22

Similar to "fetch" and "results" action the extension function
<dp:url-open ...>
http://publib.boulder.ibm.com/infocenter/wsdatap/4mt/index.jsp?topic=%2Fcom.ibm.dp.xm.doc%2Fextensionfunctions35.htm&resultof=%22url-open%22
allows to "get"/"post" from/to zip/tar archives (SOAP attachments) in XSLT.


Stylesheet unzip-l.xsl demonstrates how to do "unzip -l" command:
https://www.ibm.com/developerworks/forums/thread.jspa?messageID=14691375#14691375


Posting "zip2html" shows how stylesheets inside a zip attachment can be
executed:
https://www.ibm.com/developerworks/mydeveloperworks/blogs/HermannSW/entry/zip2html6

And because the attachment protocol provides "real" URLs this is even
possible
if the stylesheet includes/imports other stylesheets or accesses XML files
by document() calls -- see "Technical discussion" section.

Interesting, thanks. Has anyone designed and/or implemented anything
like this?

An XPath Functions Community Group might be a way to get that sort of
thing to W3C's attention in the future, by the way.

It's perfectly possible, of course, to use a DTD (or DTD fragment
defining entities) with XML Schema.

The challenge here is backwards compatibility, although it could be done
by using a different escaping character, e.g. the little-used "v v
ligature" ("w") :-)

It's interesting that I haven't seen any comments along these lines from
the MathML WG. Probably they are more steeped in the arcane lore of DTDs
and Schema Languages than the average MathML user.

Thanks for the feedback! I'd for sure like to hear more about these
topics.
