Digester couldn't care less, as long as the JDK doesn't throw
MalformedURLException.  If your parser chokes on this, it's time to get a
better parser :-).  Or, figure out what your parser *will* accept for
Windows-based file paths.  That's up to whatever parser you are using, not
Digester.

Both JAXP/1.1 and Xerces 1.4.3 work for me, on both Windows and Unix.

RE: [digester] using non URL'ed DTD's

[Tal Dayan <ta...@zapta.com>]

Any objection from the maintainers of Digester for adding a register(...,
InputStream) method ?

Internally, the digester converts anyway the URL to an InputStream. This
will allow to accept a DTD from any source (memory, database, etc) and not
just a URL'ed resource. This is supported anyway by the underlying parsers.

I may provide the code if needed.
