Syntax check on BMS edit

customer has Rational Developer for System z 7.5.

He is creating a bms. He add a map to an existing mapset. To do this he
select in the pallete the map field and drag it into the mapset. He
saved it, then compile it and receive an error.
This was the source added into the mapset:
MAP DFHMDI SIZE=(15,30),COLOR=GREEN,HILIGHT=OFF, *
COLUMN=6, *
LINE=6

The error is:

** ASMA254I *** MNOTE *** 2526+ 8,DFHMDF MACRO MUST BE
SPECIFIED WITHIN 02-DFHMD
2527+*,THE PREVIOUS MAP DEFINITION
02-DFHMD
2528+*,WHEN DATA = FIELD IS
SPECIFIED OR IMPLIED BY DEFAULT 02-DFHMD
2529+*,IN THE DFHMSD OR THE DFHMDI
MACRO.

So when customer adds a map into a mapset and doesn't add any field into
it, he should receive a warning about this, like the annotations in the
LPEX editor for COBOL programs.
