Hi olivier, and others

I think it would be very useful to have a uniform output format for  
validators. This being XML, text, or RDF is a secondary question for  
now. I'm more interested for now of the abstract representation, then  
we can choose a format. The benefits would be that we could leverage  
the development we do for one tool and reuse it for other tools. No  
needs to develop again and again the presentation layer for  
validation results in each individual tools.

CSS validator:

  - physical context: Line number
  - logical context: class names or ids
  - Message: descriptive with variations
  - type of result: warning, error, level

Markup validator:
  - physical context: line and column number
  - logical context: extract of where the error is supposed to happen
  - Message: short and long

  - physical context: line number (more than one sometimes)
  - logical context: the link which has been checked
  - Message: status code and human readable

RDF Validator:
  - physical context: line and column number
  - Message: a code plus prose

  Note: The RDF validator is a bit puzzling, for example on RDF/XML  
it exits with Fatal error if it's non well formed. So it acts like an  
XML validator in this case. It would be interesting to know what is  
an invalid RDF file when the document is well formed (for any kind of  
syntax, be RDF/turtle or RDF/XML).

Maybe we should ask Henri Sivonen, Sam Ruby as well.
