Compare the other XML outputs (most easily seen by examining subversion/svn/schema/*.rnc) where "entry" is used for the element of various kinds of lists -- lines of blame, targets of status, etc.

For now, I'd only expose the attributes of <entry> and <commit> and the
elements within <commit> and <repository>, along with the URLs. The
definitive list is:


I wouldn't expose entry's 'path' attribute because it doesn't make much
sense; in the WC case, it's already known and in the URL case, it's
always the basename, which is also known. I'd also leave wc-info,
conflicts etc. out for now.

All that said: Johan makes a good point about using keywords that are
more likely to be familiar to users; the XML-based ones are far from that.
