To me this looks like a good use case for the include transformer [1]  
& [2]:

input.xml:
<?xml version="1.0" encoding="UTF-8"?>
<root xmlns:i="http://apache.org/cocoon/include/1.0">
	<abra>
		<abrakadabra>blah</abrakadabra>
		<abrakadabra2>blah2</abrakadabra2>
	</abra>
	<i:include src="cocoon:/fromDb/1"/>
	<i:include src="cocoon:/fromDb/2"/>
</root>

sitemap fragment:
<map:match pattern="">
	<map:generate src="input.xml"/>
	<map:transform type="include"/>
	<map:serialize type="xml"/>
</map:match>

<map:match pattern="fromDb/*">
	<!-- TODO read from database... -->
	<map:serialize type="xml/>
</map:match>
