Yep: add one. For example,
# from a Unix shell prompt:
( echo "<!DOCTYPE foo SYSTEM 'foo.dtd'>" ; cat mydoc.xml ) | rxp -
For a more elegant solution, if your validator supports OASIS
catalogs (nsgls does), you can set up a catalog that will choose
an appropriate DTD based on the root element type name.
nsgmls -m /path/to/catalog -s -B *.xml
where the catalog file should contain:
SGMLDECL xml.dcl
DOCTYPE foo foo.dtd
DOCTYPE bar bar.dtd
and xml.dcl specifies FEATURES IMPLYDEF DOCTYPE YES.
A suitable SGML declaration can be found, erm, here:
