http://www.w3.org/Bugs/Public/show_bug.cgi?id=4540 ------- Comment #1 from chamberl@almaden.ibm.com 2007-05-14 04:29 ------- The keyword "copy" was introduced for a reason. The ":=" operator normally does not make a copy. Instead, if there are nodes on the RHS, the variable on the LHS is bound to references to these nodes. The variable can then be used, for example, to navigate to the parents of these nodes. In contrast, the COPY clause of a transform also uses the ":=" operator but it makes an actual copy of the nodes on the RHS. The keyword is helpful to emphasize this distinction. --Don C.
