Can't use additional namespaces with zcml-additional

[distributist]

Version 4.2.15 added "Always wrap contents of zcml-additional with a node. This makes it possible to use += assignments with zcml-additional." However I have additional ZCML that also requires an namespace added to the tag, and so won't work in this situation.

As far as I can tell, the only place to add additional namespaces is in the configure tag. Is there another place to do this, that would work with the tag wrapping?

Thank you,
