> This issue is a duplicate of ODE-369 to track the integration of XQuery into
> Ode 2.x (trunk)
> ---
> By default, the language employed in WS-BPEL queries and expressions is XPath
> 1.0. This is denoted by the default value of the queryLanguage and
> expressionLanguage attributes, which is
> "urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0". In addition, we have
> out-of-the-box support for XPath 2.0.
> Given that XQuery 1.0 is fast becoming the de-facto lingua franca for
> querying XML, it is only fitting that it be given first-class status in
> WS-BPEL. Specifically, XQuery 1.0 goes above and beyond XPath 2.0 by offering
> the capability to write conditional/switch/iterating expressions, construct
> static/computed nodes, declare functions/variables, among other things.
> To that end, we propose leveraging WS-BPEL's extension mechanism to support
> the use of XQuery 1.0 as a query and expression language. In particular,
> XQuery 1.0 will be indicated by a specific value of the queryLanguage and
> expressionLanguage attribute, namely
> urn:oasis:names:tc:wsbpel:2.0:sublang:xquery1.0".
> The context for XQuery must be initialized with a set of bindings for
> in-scope variables, declarations of in-scope namespaces and a library of
> WS-BPEL and core XPath functions. In theory, one may import external XQuery
> modules into that context in a implementation-defined way. However, the
> module feature will initially be out of scope.
> Best Regards,
> Karthick Sankarachary
