Consider the following example, inspired by some code Norm sent earlier:
<p:pipeline name="pipeline"
xmlns:p="http://www.w3.org/2007/03/xproc"
xmlns:ex="http://example.org/ns/xproc-extensions">
<p:declare-step type="ex:db-query">
<p:output port="result" sequence="no"/>
<p:parameter name="database" required="yes"/>
<p:parameter name="query" required="yes"/>
</p:declare-step>
<ex:db-query name="query">
<p:parameter name="database" value="mydb"/>
<p:parameter name="query" value="some query"/>
</ex:db-query>
</p:pipeline>
The ex:db-query component produces an output, but is not used in this
pipeline. Questions:
1) Is this a valid pipeline?
2) If it is, should the query be sent to the database (yes, no,
implementation dependent)?
