Understandable. As I said about RDF a couple of days back, two
formats are almost never better than one.

As a search engine writer, my interest is in common conventions
across different formats. So far, I've only found one thing that
is common to almost every DTD -- the first <title> tag is the
title (the major exception is the NAA "adex" DTD for classifieds,
where <ad-slug> is the closest thing to a title).

HTML has some conventions for search-engine metadata (title, 
description, keywords, robots). With XML, the administrator
needs to map each DTD to these elements -- more work, more
chance for error. And if the data is not there, not in a parsable
format, or in a separate metadata file, the search engine is

I expect to ship our next release pre-configured for NITF,
but I sure would like to see some common practice beyond <title>.
Mostly, our customers would appreciate it, and the people doing
searches would get better results.
