XOM API for Processing XML with Java

[Wolfgang Hoschek <whoschek AT lbl.gov>]

Take JDBC PreparedStatements as an analogy. A query is compiled and 
optimized once (an expensive process in particular for optimizing 
engines such as Nux/Saxon), then executed many times, each time with 
different variables aka parameters. Say variables customerID, SSN, 
sectionTitle, timeRange, etc. For example, the Nux XQueryPool addresses 
such usage scenarios in a easy-to-use thread-safe manner.
