Can I change the boundary delimiter that CXF generates for multipart messages?

Issue

Our SOAP client has a problem with a colon in the content-type's boundary tag. Using CXF we have implemented a SOAP service which also returns an attachment. Currently the boundary is a UUID (e.g. uuid:cd43dc28-34e0-4f9e-9b2b-ff7a073c4bff) with a colon.

• Is it possible to customize the value of the boundary? The client has a problem parsing the content-type/boundary due to the colon in the uuid.
