-----------------------------------------

This makes custom EL functions not useable in pages.xml for example.

> Custom Facelets EL functions define established through xml or a custom AbstractTagLibrary do not pass the barrier to JSF but are segregated purely to facelets.  So, one can't use Expressions.instance().createValueExpression(...) with a custom el function in it as it doesn't existing in the JSF FunctionMapper.
> There should be some mechanism to either import the existing functions, or to register the functions with JSF alongside of Facelets.
