Spenser,

run-xquery.xpl is called from the XQuery sandbox written in
XForms. The input document is available to the user as text in a
textarea, which translates at the XForms instance level into a string
under a root element called <input>.

Then that document is passed to run-xquery.xpl, so the string content
under <input> has to be parsed (saxon:parse()) before being fed to the
"data" input of oxf:xquery, which expects an XML document containing
the document to process, and not a string under an <input> element. So
the "data" input of oxf:query will look like:

<company>
   <department ...>
     ...

Now if I understand well you build a document that looks like:

<input>
   <company>
     <department ...>
       ...

I am not sure why you want to do this ;-) And not sure whether you are
trying to make use of this in the sandbox, or in a different scenario.

In any case, what do your input document and query look like just
before reaching oxf:xquery? To figure this out, use a debug attribute
in XPL on the "config" and "data" inputs of oxf:xquery.
