That doesn't make sense. A NULL value means the field is not present in this record. The TID must be present.
A zero PMAP bit for a field means the field is not present _on the wire_. To answer your earlier question, "Yes there are FAST data sources that omit the TID on the wire, relying on the implicit copy operator for the template ID. For this to work, the PMAP must come first.
If this is a problem for your implementation, I might respectfully suggest you change your implementation rather than trying to change the protocol.
