I found only one attempt to create such compiler - http://sourceforge.net/projects/xsltc/. But this project is dead for decade already. Are there any other examples? Opensource or commercial?
Are there any fundamental technical difficulties with building such software? With the whole approach of compiling XSLT natively?
I suppose there are good use cases for using it - places where we don't need to change XSLT but still would like to get higher performance (and probably, lower memory requirements).
Are there any other reasons this software may be not so efficient as it looks? - Are interpreting XSLT processors as efficient as compiled would probably be?
