URecords. pas defines several entity types that do not appear in the DCAL manual:
enthol - anyone have a description and/or explanation of fields?
entxref- appears to be unused according to the notations. How exactly is an xref stored in a document. In an earlier post devinder refered to attributes playing a role, but how exactly are they treated?
entBlkAttDef - This looks like it has something to do with a new text entity or does it have to do with the addition of truetype fonts in Datacad? There are lots of fields and even more questions.
EntSuper - Does this have to do with placing bitmaps into a drawing? There does not appear to be enough here to establish an entity in the drawing.
