When ZPT's (version 1.4) HTML parser finds an incomplete entity (or character)
reference, it restarts parsing at the start.
If it encountered a macro definition before the incomplete
entity reference, this will lead to a

TAL.TALDefs.METALError: duplicate macro definition: ....

exception, as shown by the attached ZPT.

Patch attached...
