Adding support for XML validation with XSD

[dngferreira]

This could be an interesting enhacement for the xml filter.
Is this planned? How can I help?

[jordansissel]

+1 I like this idea.

[jordansissel]

As far as how to help, can you describe what you want the behavior to be? (I have some questions I'd propose for clarifying behavior, but I want to see what you want first)

[dngferreira]

To start with I think it should be similar to the way grok tags the data when it cannot parse.
Tag the document with an "xmlvalidationfailed" for example.
Add support for xsd format as a validator.

Later it could be extended for other formats like Relax NG and others.
But I think a tag stating if it was parsed or not and XSD support would be enough for 80% of the cases.

@jordansissel do you have any other thing you would want to add?
