Never having given it much thought I just figured there might be a process of optimization whereby the parser could save some power in cases where entities lead to nodesets. Then again such optimization if it could be achieved would prob. be at the expense of the plain text entities, you know where &fred; expands to fred flintstone :) I always hated those examples. Another part where I was thinking a canny use of entities could save power was in the declaration of xpaths, in fact I had a situation where I had to repeatedly do a bunch of long comparisons along the preceding-sibling following-sibling axises(axii?), I replaced parts of my expressions with entities and it seemed to me that I experienced a speed up in processing. Could be self-hypnosis. Am not sure. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
