Allow partial indexes in all editions

IDS 14.10 contains this important new feature:

https://www.ibm.com/support/knowledgecenter/SSGU8G_14.1.0/com.ibm.sqls.doc/ids_sqs_partial_index.htm

"Partial indexes avoid indexing common values. As the query searching for a common value will not use the index, there is no point in keeping those rows in the index. This reduces the size of the index, which will speed up queries that do use the index. It will also speed up many table update operations because the index does not need to be updated in all cases."

We understand that tables comprised of multiple fragments (partitions) is part of the parallelisation features reserved for Enterprise Edition. Unfortunately, partial indexes has been implemented using the FRAGMENT BY EXPRESSION (or PARTITION) syntax, and this is rejected on lower editions (except Developer). Using the example table from the above documentation page: 

CREATE INDEX idx2 ON tab1 (n2)
FRAGMENT BY EXPRESSION
(n2 IS NULL) INDEX OFF,
REMAINDER IN datadbs;

26453: Fragmentation is not supported in this edition of IDS
