I'll wager this is because you are using a TEI DTD which defines
"simple" as the default value of list/@type?

I don't know about this one ... but I notice the text of your assertion
says "Blockquote" while the XPath says "blockquote".

Try

<sch:rule id="r14" context="placeName/*">
           <sch:assert role="M" test="self::country|self::region|self::settlement"
           >placeName must contain only country, region, or settlement elements.</sch:assert>
</sch:rule>

The test should be ".='state' or .='county' or .='province'"
