to quote the p:filter definition in the latest editors draft

--------------------

The p:filter step selects portions of the source document based on a
(possibly dynamically constructed) XPath select expression.

<p:declare-step type="p:filter">
     <p:input port="source"/>
     <p:output port="result" sequence="true"/>
     <p:option name="select" required="true"/>
<!-- XPathExpression -->
</p:declare-step>

This step behaves just like an p:input with a select expression except
that the select expression is computed dynamically.

--------------------

if the select expression is computed e.g.

<p:option name="select" required="fn:concat(a/text(),b/text(),//c/text())"/>

I am guessing this is against source input ... does this need to be
clarified in the text of the p:filter definition ?
