Hi all,

I need a Schemtron rule which indicates an error when <li> elements do not have any child elements. No error schould be indicated for <li> elements with an "conkeyref" attribute and also for <li> elements which are children of any element with a "conkeyref" attribute.

I have defined two separate rules...

<sch:pattern id="Check_LI2">
    <sch:rule context="li[not(@conkeyref)]">
      <sch:assert test="*">List does not contain any child elements</sch:assert>
    </sch:rule>
</sch:pattern>

<sch:pattern id="Check_LI3">
    <sch:rule context="li[not(parent::*[@conkeyref])]">
      <sch:assert test="*">List does not contain any child elements</sch:assert>
    </sch:rule>

</sch:pattern>

... but I think I need to combine them into a single rule with an OR or AND operator.

<sch:pattern id="Check_LI3">
    <sch:rule context="li[not(@conkeyref)] OR li[not(parent::*[@conkeyref])] ">
      <sch:assert test="*">List does not contain any child elements</sch:assert>
    </sch:rule>

</sch:pattern>

However, this syntax is invalid. Can somebody help me?

Regards,

Frank
