I can just confirm Leo's observation. We (or anyone else) might need to detail this somewhere in our documentation. Am 30.03.2012 02:09 schrieb "Leo Wörteler" lw@basex.org:
Hi,

Using the REST interface, I'm currently able to do the following:
<rest:query xmlns:rest="http://basex.org/**rest http://basex.org/rest"> rest:text$foo</rest:text> <rest:variable name="foo" value="bar"/> </rest:query>
...and get back "bar" as a result. Note the lack of a "declare variable $foo external" line.
I haven't read the spec to determine permissibility of this behavior, but it does come in handy at times (particularly, for permitting maximally terse one-liners). Is this something likely to go away in the future?
I don't think this "feature" will disappear any time soon, because it's so widely used and doesn't cause any problems. It isn't backed up by the spec though. Every free variable $x in a query is treated as if it was declared as `declare variable $x external;`.
Hope that helps, cheers, Leo ______________________________**_________________ BaseX-Talk mailing list BaseX-Talk@mailman.uni-**konstanz.de BaseX-Talk@mailman.uni-konstanz.de https://mailman.uni-konstanz.**de/mailman/listinfo/basex-talkhttps://mailman.uni-konstanz.de/mailman/listinfo/basex-talk
