Validate document against schema

[Artem Karpenko]

Hi,

I am looking for possibility to validate document that is about to be 
inserted against schema to check if addition of document will fail or 
not w/o actually making an insert. Is there a way to that? I'm doing 
update from inside the Solr plugin so there is an access to API if that 
matters.

Thanks in advance,
Artem.
