Bug #3993

Updated by Michael Kay over 3 years ago

(1) Setting the configuration property `Feature.DISABLE_XSL_EVALUATE` does not work. It says the property is not recognised. 

 (2) The specification says that when `xsl:evaluate` is dynamically disabled, any `xsl:fallback` child instructions should be evaluated. We do not have the capability to do this, because `xsl:fallback` instructions are discarded at compile time. 

 (3) The result of `system-property("xsl:supports-dynamic-evaluation")` does not take into account whether or not xsl:evaluate has been disabled. 

 (4) Under Saxon-HE, xsl:evaluate is always statically disabled, so xsl:fallback should take effect, but this is not happening 

 (5) Under Saxon-PE/EE, if xsl:evaluate is statically disabled by setting a configuration property (or by running without a license), xsl:fallback should take effect, but this is not happening, even with JIT compilation of template rules disabled
