[Sab] new features in Sablotron 0.50

[Shah Hitesh Bhavanji]

Hi, I went through the http://www.gingerall.com/charlie-bin/get/webGA/act/sablot_man.act for the documentation about the features implemented in 0.44, however was curious to know the same about ver 0.50.   I would be thankful if anyone from you could quickly update of what changes are implemented in 0.50 other than that of xsl:sort.   Thanks and Regards, Hitesh.
