Crimson and dtd dependence

[Debbie Wilson <De...@ca.ibm.com>]

I recently found that if you have a dtd specified in an xml file and that 
dtd file does not exist, you get the following:

!STACK 0
java.io.FileNotFoundException: 
d:\EclipseEnvs\3.0\I20031113Data\eclipse\runtime-workspace\abc\xxmyDTD.xml 
(The system cannot find the file specified)

...

In my particular case, I specified that the parser was to be a 
non-validating parser.  I don't really need the dtd to be present. 

Is there a place I can log this as a crimson bug?  Am I likely to get a 
fix for this problem or is there really no further development on crimson? 
 Does anyone else have experience with such an issue?

Almost everyone has experience with this issue and it is not a
parser "bug".

If you declare a DTD in your XML instance, then the parser *must*
resolve it. This needs to happen even if you set the parser to be
non-validating.

Every XML framework needs to employ a "Catalog Entity Resolver", i.e.
http://xml.apache.org/commons/components/resolver/
