Well, this has been discussed, and I think that Malcolm is broadly 
favourable in principle, but it ultimately depends upon both of us finding 
time and effort to do the requisite merging.  I did talk about my changes 
with Malcolm as I applied them, so I would hope there's not too much there 
that is incompatible with his vision for HaXml.

Meanwhile, when I have time, I hope to package my version as a Cabal 
package so that those who want the features I added have a reasonably easy 
route to using them.  Until then, the best I can offer is the code on my 
web site.

When making changes, I did try fairly hard to maintain as much backward 
compatibility as I could -- adding features and interfaces rather than 
displacing them -- though I think there were a couple of unavoidable type 
signature changes.

The most intractable incompatibilities may be incompatible XML handling 
where I have made changes to follow the official specification more closely.

Sadly, no :-(
