XML Parsing in Go

I'm looking into a project that will do some XML parsing and likely be
implemented in Go. What do folks think of the available libraries? All
I see so far seems to be based on the rather broken notion of data
binding. (One more time: XML documents are not structs.)

Is there any rough equivalent to SAX, DOM, or XOM for Go that supports
XML in its full generality? For now I can live without external entity
resolution. Validation would be nice but is not absolutely essential.
I do need to support mixed content and elements that don't necessarily
appear when and where you expect them, though.
