Replacement for TNWeb getContentPartBytes?

Hi,
I currently am able to retrieve the xml string for a BizDoc using the wm.tnweb.querySvc:getContentPartBytes package (using IS6.5). We are moving to IS 7.x and understand that TNweb is gone … is there another way I can get the xml string for a given BizDoc? In case it matters, we will not be implementing MyWebMethods server until the next version of our system.

Thanks!!

wm.tn.doc:getContentPartData with getAs set to bytes.

wm.tn.doc:getDeliveryContent is another service that may fit what you need.
