Perhaps, but how many processors have such an optimization? It seems to me that it would only be useful if you had stylesheets containing perhaps hundreds of match templates, where the mathematical exercise of template matching would start to take longer than categorizing the template rules, pre-evaluating the select expression, and making the appropriate comparisons. At any rate, at some point you have to evaluate the expression, and my assertion is going to be no less valid for that. "parent::node()/child::*[generate-id()=generate-id(current())]" is going to be less efficient than "self::x", and "self::x" is less efficient than ".". - Mike ____________________________________________________________________________ mike j. brown | xml/xslt: http://skew.org/xml/ denver/boulder, colorado, usa | resume: http://skew.org/~mike/resume/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
