Caro, Samuel asked:

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:
