This function returns all the attributes with the given attribute definition
attached to any entity within the given part. If the attribute definition is
PK_ENTITY_null, all attributes are returned, of any type.

assembly and its instances are returned.


The output array attribs is optional. If it is set to NULL, the function
will only compute the number of such attributes within the part.
