There's been discussion here about techniques for passing queries to an XQuery
processor. There was a suggestion Java programs should parse them and pass them
as serialized abstract syntax trees (one benefit being compile-time type
checking). That seems a reasonable alternative as an option, but not as a
replacement, for sending XQuery strings down the wire.

It could be jet lag speaking but that's my impression of the "strings or not?"
discussion.

The issue is relevant to ad hoc queries but it's moot for repetitive queries,
such as for generating a monthly publication. XQJ provides for prepared
expressions. We'll undoubtedly see XQuery implementations that provide stored
queries. In that context, the XQJ client passes execution time parameters.
