encoding/xml: XML namespace prefixes not fully supported

[gopherbot]

by anthonyeden:

It is possible to create a prefix on elements by simply defining the prefix as part of
the name in the XMLName declaration, but the xmlns attribute is output without the
prefix. Example: http://play.golang.org/p/KeIHB4_z5L

Thus it would seem that the encoding/xml package can only deal with document-level
namespaces, not nested namespaces, is this correct?

Comment 4:

This generates:
<example:foo xmlns="urn:example"></example:foo>
Am I correct in believing you require:
<example:foo xmlns:example="urn"></example:foo>
?

Comment 6 by anthonyeden:

FWIW, I'm creating an RFC5730-RFC5733 implementation in Go, which is what triggered this
requirement.

Perhaps this will help explain the shortcomings here.

The lack of good support for namespace prefixes does seem to be affecting us here too
