xsl:supports-serialization | This property returns the string yes or no , depending on whether the XSLT 2.0 processor supports serialization or not. |
xsl:supports-backwards-compatibility | This property returns the string yes or no , depending on whether the XSLT 2.0 processor supports running in backward-compatibility mode. A processor that does not support this mode will report an error if version=“1.0” is specified. |
xsl:supports-namespace-axis | This property was introduced to the specification by means of an erratum, so not all processors will support it. It returns yes if the implementation recognizes the namespace axis, or no if it does not. An implementation that has not been updated to recognize this property will return a zero-length string. |
