[xml] What is the best way to implement semantics?

["John J. Boyer" <director chpi org>]

In my xmll to braille program I have libxml2 create a parse tree of the 
document. I have written a basic tree-traversal routine. What is the best 
way to implement semantics, that is, to interpret elements and their 
attributes? Is there code or documentation that I should be looking at?

I am thinking of imllementing Docbook and Daisy directly. How can I tell 
which one I have?

Other xml formats will be converted to one of the above two using xslt. Is 
this realistic?


Thanks,
John
