Calling an embedded content parser

Hi all,

is it possible to call an embedded content parser through the API?

I have implemented a custom file type (actually XML) in c#, with a custom parser, renderer, verifier etc. Some of the tags of this XML may contain embedded HTML. Is it possible somehow to process the embedded HTML with the already existing parser/renderer components of Studio? I have not found any description/example in the SDK, but maybe I searched at the wrong place.

Thanks in advance, 

Tamas
