    Why are you using a DTD, which is the antithesis of Ada? A schema which
is the semantic equivalent (translation) of a collection of Ada types would
be far more appropriate.

    Don't worry about it. I said that I thought that the first version of
    the XML document was not something I would be comfortable posting, but I

    would send copies to anyone who wanted to review it. Stephane Richard
    was willing to do so. Unless there are significant changes, or more
    people who want to take a shot at the current XML state, I will probably

    post version 0.2 to comp.lang.ada tomorrow. Another potential delay is
    that I am probably going to write an XML to HTML converter this weekend,

    so you can look at the HTML to make comments.
    
    No intent to exclude anyone, but XML is still not all that common a
    language, and I felt the intersection of those who knew XML well enough
    to comment, and were also interested in the registry project would be
    pretty small. Hmmm. Actually, why not? Here is the current XML
    DOCTYPE, and the start of the registry declaration. If you want a
    snapshot of the whole thing, send e-mail. But, please, only if you are
    willing to read it and comment.:
