That page gives 404 Not Found at the moment, but http://wcs.emprear.com/ can 
still be used to reproduce the issue.

The OMA website serves xhtmlmp12-form-1.mod as application/octet-stream and 
without indication about the content's character set, which doesn't play well 
with the underlying libxml2 parser in the validator, which defaults to UTF-8 
(and AFAIK nobody has yet checked if something could be sanely done to that).

$ HEAD http://www.openmobilealliance.org/tech/DTD/xhtmlmp12-form-1.mod | grep 
Content-Type
Content-Type: application/octet-stream

the Doctype

I think that (removing it from the drop-down list) would be a bit premature, 
I'm going to try contacting OMA and see if something could be done to this.  
And the validator does not contain a copy of the XHTML MP DTDs, it fetches 
them on demand.  This is for licensing reasons, the OMA use agreement does not 
allow distributing their DTDs which would pretty much happen if the DTDs would 
be committed to validator's source code control repository [0]. 
http://www.openmobilealliance.org/use_agreement.aspx

The same use agreement also prohibits making modifications to the DTDs so even 
if they could be redistributed, it couldn't be modified so that it'd work with 
the validator.  (Modifying might not be necessary if the DTDs would be 
installed locally though, haven't checked that closely.)

[0] It would be possible to do add them locally on validator.w3.org without 
going through source control, but this would require specific 
customization/maintenance for those instances of the validator.
