This looks nice and compact Using opDispatch to specify the tag (I guess 
that is what you are using to create a tag "book" by calling xml.book()) 
feels like misusing opDispatch, though. Does it add readability in 
contrast to passing the tag as a string to some function?

How do you write a tag named "tight"? Or a tag calculated at runtime?

Something more conventional would be

	xml.tag("book", attr("year", book.year), { ...

but I'm not sure that pairing the attribute name and value adds 
readability or mere noise.
