    One thing I noted while skimming through that issue and the linked 
    conversations: There were statements along the lines of "once we can use 
    guile2, it gets easier" (because of the sxml module). Now we know since 
    (I think) May that it is possible to produce a production-quality 
    LilyPond using Guile 2.2. (I used Jonas' experimental binary release for 
    quite some time over the summer in my everyday work, without any problems.)
    
    So, while there are no regular official binary releases with Guile2 yet, 
    I think it would now be quite acceptable to use Guile2 features in a 
    possible XML export engine.
    
I totally agree that it would be acceptable to use Guile2 features.

Unfortunately, I think that Guile2 only helps with the Scheme structure to xml 
conversion, making the "routine" part of the programming much easier.

I don't think that Guile2 will provide any help with what I think the 
challenging parts of the problem are -- converting Lilypond data structures 
into an appropriate Scheme structure for moving to xml.  But I could be 
completely wrong.  Jacques certainly would know more about this than me.

Thanks,
