I visited the DAVEML web page, but did not seem mention of an XML Schema for DAVEML. I seem to recall some mention of the existence of a schema. Is there a Schema for DAVEML? I suspect that there is a way to convert a DTD to a Schema. I'm using oXygenXML as an editor.

Hi, Jon!
We haven't put an XSD (XML Schema Document) together for DAVE-ML
since the jury seems out on wholesale acceptance of XSD's, while DTD's
(Document Type Definitions) seem to be a universally understood schema
description.
The DTD is available from
<http://daveml.nasa.gov/DTDs.html>.
There are translators to convert DTD -> XSD but I don't have
any experience. XSD is a very rich (and some say complex) syntax, so I
don't think there is a conversion the other way.
Internally I use RNC (RelaxNG compressed) schemas to handle the
DocBook-based reference manual and actually to generate the DAVE-ML
DTD + reference sections. This compact and powerful, but not
universally accepted, schema description comes from James Clark of
thaiopensource.com:
