While Els message pretty much covers everything, I'd like to add just a bit
on the XML case issue.
XML is case-sensitive with respect to SGML "names." This means that if the
DTD declares the name of an element as scopecontent, then the tag in the
instance must be in the same case: <scopecontent>. <SCOPECONTENT> and
<ScopeContent> will be flagged as errors by an XML validating parser. SGML
parsers will not object because SGML is not case-sensitive.
Author/Editor converts are all element names in tags into uppercase. The
EAD DTD declares all element names (and all names) in lowercase. Obviously
this will be a problem when using Author/Editor instances as XML instances.
Fortunatley James Clark's suite of SGML tools now includes a utility for
converting SGML instances into XML instances. Among other things, it will,
if issued the right command, convert uppercase element names into lowercase.
