Hi Philip,

You are right, err:XS0012 does not exist anymore. It used to be used in
the older drafts of the specification:

err:XS0012: It is a static error if the port given does not match the
name of an input port specified in the step's declaration.


My guess is that you get this error because of this:

<p:xquery>
  <p:input/> <--- p:input with no port
  <p:input port="query">
    ...

You can't have a p:input without the @port attribute. If you want the
p:xquery step to use the input of the main pipeline as the XQuery
context item, you can either do:

<p:xquery>
  <p:input port="source">
    <p:pipe step="config2xml" port="source"/>
  </p:input>
  <p:input port="query">
    ...

or you can simply leave out the binding for the "source" input
completely (because it is a primary input port on p:xquery, it will get
connected to the input of the main pipeline automatically):

<p:xquery>
  <p:input port="query">
    ...

--

And yes, Hendrik is right that you will have to either wrap your XQuery
document in the c:query wrapper, or use p:data instead of p:document.

Vojtech
