Claus Ibsen commented on CAMEL-1537:
------------------------------------
Willem you was a bit to fast there to commit the patch.
We already have the pieces in the core, and all was needed was just to add the
validate in the DSL which hooks up with the Predicate/Expression concept of
Camel.
And it can be integrated with XML by requiring an ExpressionNodeDefiniton (i
think thats the name, but see eg. DelayDefinition).
Then that Expression is just evaluated as a Predicate and if its false an
exception is thrown.

> The current validator is a component and its a bit clumsy as it throws an
> exception if validation error.
> So if we have a nice Predicate for it, it can be like a xpath predicate or
> the likes.

> [17:58] <ulhasb> jstrachan: thanks for the quick responses
> [17:59] <cibsen> jstrachan we should maybe have a predicate for schema
> validation
> [17:59] <cibsen> then you can route it a bit more nice without try .. catch
> [18:00] * fbolton has quit ("Leaving.")
> [18:03] * gertv has quit (Client closed connection)
> [18:05] <jstrachan> cibsen: yeah
> [18:05] <jstrachan> cibsen: maybe a kinda predicate language using the other
> validators? filter().validate(theValidationEndpointUri).to("blah")
