Use EDI parser on its own

Is it possible to use just the EDI disassembling/assembling pipelines 
withouth the rest of BizTalk's EDI infrastructure? i.e. parties?

We have an interesting situation where EDI messages are recieved through a

separate VAN, and we need BizTalk to pick up the EDI messages from the 
filesystem, parse them in to nice XML do***ents, then load the data in to
a 
database.

Thanks!
