Can I use a property loaded from property-placeholder to make a context import dynamic?

Code:
<context:property-placeholder location="classpath*:/enterprise.properties"/>
<import resource="classpath*:/Fsb${jdbc.ctxType?:Jdbc}-context.xml"/>
Properties File
Code:
jdbc.ctxType=JTA
So this way I could change the type of context file that is loaded based on a property.

Also, can I do the same thing to make a bean ref name dynamic?

Code:
<bean id="personBusinessService" class="com.foo.PersonBusinessServiceImpl"
			  p:personUidDataService-ref="personUidDataService${personUidDataService.sib?:Api}"	
			  p:identifierLookupSearchService-ref="identifierLookupSearchService${identifierLookupSearchService.sib?:Api}"	
			  p:contactPointBusinessService-ref="contactPointBusinessService${contactPointBusinessService.sib?:Api}"
    />
Properties File
Code:
personUidDataService.sib=Stub
Thanks...also, if this isn't the right forum group...please let me know.
