For sure, but that's really out of scope for what I'm doing.  The "task"
should be understood before the stuff I'm specifying happens.

Sure, there's an infinite number; edit (as you say), convert, compress,
summarize, reverse, encrypt. Basically, anything you can do to a blob
of data.

Consider "summarize".

For a compound document including XHTML & SVG, we could activate a
"XHTML summarizer" for the XHTML content, and a separate "SVG
summarizer" for the SVG content.  The end result is a summarized
version of the whole document.  Right?

Ditto for every other task.  A compound editor could activate an SVG
editor in-place within a WYSIWYG XHTML editor.  A compound compressor
could activate compressors optimized for each namespace, yielding
superior compression.  etc..
