Thread:Help talk:Adding subobjects using Semantic Forms/Concrete example would be great/reply

Hi - unfortunately, Page Schemas doesn't support #subobject yet - that needs to be added. For now, it only supports the similar #set_internal call, in the Semantic Internal Objects extension. So you could either install SIO and re-edit the schema, or modify that multiple-instance template, after it's generated by Page Schemas, by taking out all its current SMW property tags and replacing them with a single #subobject call.
