[xml] Validate single elements against RelaxNG

[Torsten Radtke <torsten radtke mac com>]

Hello there,

I am trying to validate a single node in a document with  
xmlRelaxNGValidatePushElement, xmlRelaxNGValidateFullElement, and  
xmlRelaxNGValidatePopElement, but I only receive correct results if I  
validate the root node.

Is there a possibility to validate nodes at an arbitrary position in  
the tree?

Best regards,
