Yes. I think we need to take the Document, serialize it as a String or
temp File or whatever, then reparse the whole thing back into a
Document using Saxon. It's a bit redundant but then presumably the
resulting Document contains line number information relevant to the
moki document itself.

Exactamundo.

Yeah but I think the CSS case is easy. There's no XPath for CSS; it's
all got to be parsed out in Java anyway. I think our needs vis-a-vis
CSS are so simple that this is fine (but I'm not sure anybody is on
board with me here?). The CSS is in the moki doc, and can also easily
be parsed into an array of Strings, one per line. Line number is
trivial to determine then in any Java code testing CSS.

Fair point. I think this is why we want a "raw" copy of the response,
including everything, as well as a copy of the nodes somewhere within
moki (which won't include DOCTYPE or XML header, no). I don't think
it's a big deal if line numbers are reported relative to the latter,
which is already not quite the same as the original doc.
