Subject: [xsl] XSL processor version detection stylesheet with XSLT 2.0 properties From: Tony Graham <Tony.Graham@xxxxxxxxxxxxxxxxxxxxxx> Date: Mon, 01 Oct 2007 10:17:32 +0100 |
The XSL processor detection stylesheet [1] referred to from the XSL-List
Guidelines predates XSLT 2.0 by several years, so it doesn't use the
additional system properties defined in XSLT 2.0 [2]. It also omits the
'xsl:version' system property, which at the time had only one possible
value.
The version below uses all the system properties defined in XSLT 2.0:
