[xsl] Does anyone know the difference between Saxon-HE and Saxon-B?

[Chris Wolf <cwolf.algo@xxxxxxxxx>]

I don't see Saxon-B mentioned on the Saxonica website,
where I would expect it, i.e.:

http://www.saxonica.com/documentation/about/historical.html
http://www.saxonica.com/feature-matrix.html

...however, it's on Sourceforge:

http://sourceforge.net/projects/saxon/files/Saxon-B/9.1.0.8/

For the current time, I only need the functionality of Saxon-HE,
but with the "evaluate()" extension function, which seems to be
disabled on Saxon-HE but not Saxon-B, 9.1.0.8.

Thanks,

Chris Wolf
