Another way to do this is by reversing the roles of the files by storing
data as external general parsed entities and define the referenced entities
in the document.

dated.xml:

    <?xml version="1.0"?>
    <!DOCTYPE dated [
        <!ENTITY datable SYSTEM "datable.xml">
        <!ENTITY date "17/03/99">
    ]>
    <dated>
    &datable;
    </dated>

datable.xml:

    <?xml version="1.0"?>
    <datable timestamp="&date;">
        blah blah
    </datable>


This form of role reversal technicque can be quite powerful when used
properly.

Best,
