Well, it seems to be fixed, I saw you committed the changes ;-)

While re-thinking about it, I realized that, whilst we need to validate 
against both DTDs, the detailed report the checker should return should 
be against one and only DTD. mobileOK doesn't prescribe the DTD to use 
(it only prescribes the fact that a FAIL is returned).

I felt it made more sense to always return errors against the XHTML 
Basic 1.1 DTD because:
  1. we don't validate the page against XHTML MP 1.2 when it is valid 
against XHTML Basic 1.1
  2. apart from the "start" attribute on the "ol" element (and maybe one 
or two additional attributes?), XHTML Basic 1.1 is a superset of XHTML 
MP 1.2.

I updated the code consequently.

I also included a note in HTTPXHTMLResource.java to point out that 
exceptions thrown by the SAX parser are ignored for the moment. I don't 
know when such exceptions are thrown, provided they are. But ignoring 
such exceptions means that the checker will continue its execution as 
though the page was fully validated (and will only return markup errors 
encountered when the exception was thrown).

As you probably noticed, I spent some time digging up in the code to 
debug it.
There remains bugs, but no "blocking" bugs AFAICT (at least for the time 

I still haven't updated the online checker, but should do so in a near 
future. I keep you updated.
