Oracle will implement the scenario if enough people ask for it; the
chances of you being rich as Bill are much much smaller.....

no. My imaginary XSL script operates on a tree called $X. Currently,
$X is built in memory from parsing a text XML file, but in XWorld, it
a tree representing a portion of my database (I extracted a subset
with a conventional SQL query, maybe). My "id(@foo)" operates within
$X, and works just like in current XSL processing.

so, maybe I am using 'key("Cuchulain")', not id(). Its not
unreasonable to suppose that my initial definition of $X, on which my
script is to operate, has the Irish parliament members in some
subtree, uniquely identified.

its not half as bad as the lottery. I was basing my suppositions on
published statements by Oracle people about how they see the
future. Of course, they may not implement it, but unless I completely
misunderstood, they plan to let me access my Oracle database using
XSL. Whether they do or not, it seems a feasible plan.

perhaps the Oracle guy who is on this list should comment, not me!
