Hi,
In the meantime, I set 'name' attribute of the extendedDataElement to
"Required by parent", remove the default value, and define a
substitution rule for this 'name' attribute. If the rule does not match
the given pattern, name is 'empty; and the containing
extendedDataElement is not created.
This works - I wonder, however, if this is the best way to do it.
Thanks, chris

Hi Chris:
I think use "Required by parent " attribute is a correct way to do it.
You can check the Required by parent check box of 'name','type' or
'value' attribute, then create substitution rule to set an invalid value
to that attribute when the given field in record is not present. You can
check Common Base Event format specification
http://www.eclipse.org/tptp/platform/documents/resources/cbe 101spec/CommonBaseEvent_SituationData_V1.0.1.pdf,
to see what are valid values for these attributes.
