After digging into this a bit more, I suspect that this does not work
because the
JAXP validation framework implementation used does not support DTD
validation.
This is not obvious from the documentation, because the higher level
docs document
an abstract interface, and note all of the known possible values, not
just those
currently implemented by the lower levels.
[ So I'm doing validation from flowscript instead. ]

Does a grammar have to be specified in the sitemap to use DTDs as
the schema ?
What is the proper grammar specifier ?
I've tried using <grammar>http://www.w3.org/TR/REC-xml</grammar>
as well as trying 'Validator.GRAMMAR_XML_DTD' and 'GRAMMAR_XML_DTD'
and they all result in the error:
org.apache.cocoon.components.validation.ValidatorException:
Unsupported grammar language
With no <grammar> defined, I get:
java.net.MalformedURLException: Invalid System ID
( I also tried using the DTD URL in the src attribute for the
transformer, and I get:
org.xml.sax.SAXParseException: The markup in the document preceding
the root element must be well-formed.
but at that point, I'm just flailing around trying to figure out
what's wrong. )
How do you use this block to validate against a DTD ?
