How to find the XSLT version that you are using ?

In order to know the XSLT function we are currently working, use the following function:

system-property('xsl:version')

Ex: create a variable and print the XSLT version as follows:

 <xsl:variable name="XSLTVersion">

    <xsl:value-of select="system-property('xsl:version')"/>

  </xsl:variable>
