In DSSSL, at least, it would be probably unmanageably difficult, at least not in the general case -- the problem is that someone could use character data (perhaps after much arbitrary manipulation) later in the document to decide what to select earlier, and vice-versa, using DSSSL's navigational functions. For example, in DSSSL, I could specify something like the following: a. Take all of the character data of this element b. remove all whitespace c. reverse the order of the characters d. remove every character where its Unicode value mod 7 is 0 e. look up the resulting string in a top-level a-list f. process all elements in a second document that have a 'foo' attribute whose value is lexically <= the a-list value, and concatenate their character data g. process the element in the first document with a 'bar' attribute containing a number equal to the number of characters extracted from the second document in step f. Hopefully, things aren't quite this bad for XSL. Good luck -- I'll be very excited if you can solve this.
