in order to be able to handle large binary attachments in our MPGW policy, I configured the object to utilize the attachment streaming mode.
Everything works fine (using no-xml-processing rules for the attachment).
But it seems that the side effect of using the attachment streaming mode is, that the attachment-byte-count restriction does no longer apply. The max-message-size is used for all parts for the message instead - even the non-xml parts.
This is highly unfortunate, because we definitly want to restrict the root XML part of the messages (because those are processed in the datapower and not just streamed through it), but want to allow much larger attachments (for instance 16 Mbytes for the root part, up to 2 GBytes for the attachments).
It there any way to achieve this with the current (we're using 18.104.22.168 on XS-40, XI-50, XG-45 and XI-52 devices) firmware releases?
