No way to unset registered PHP functions in XSLTProcessor::registerPHPFunctions()

Hello all, During writing tests for the Berlin PHP Testfest, I noticed that you may call the XSLTProcessor::registerPHPFunctions() several times and that the new functions get appended to the allowed list of functions. Problem is that there is absolutely no way to un-register allowed functions or at least reset the list by using an empty array (which would be bad style) or null or false. Shouldn't that possibility be added? Currently, the only way to reset the list is to create a new processor object. -- Regards/Mit freundlichen Grüßen Christian Weiske -= Geeking around in the name of science since 1982 =-
