I find "integer" very limitative. It should be
"implementation-defined" as generate-id()

I agree.

May I propose to have a component for that

<p:declare-step type="p:detect-duplicates">
     <p:input port="source"/>
     <p:output port="result" primary="false"/>
     <p:option name="fail-if-duplicates" value="false"/>
     <p:option name="select"/>
</p:declare-step>

which will evaluate sequentially the nodes given with the select expression
