If character are defined with an id (numeric or character) in one file, and the item descriptions use these ids through idref or through xml-schema keyref means:

How can a validating parser validate the schema, including keyrefs, without having to include the entire character definition in each of 1000s of taxon description xml files? Can the ids for idref/keyref be declared to be in a separate file?

I could not find a standard xml-include command. I know there is one defined for dtds, but that is all I could find.

Can the xml experts help?
