[EP-tech] epc:if tests for the existence of values in a compound field

[Ian.Stuart at ed.ac.uk (Ian Stuart)]

I'm writing a citation schema, and when it comes to compound fields, I 
don't want to have a table with just the column headings.

I tried

       <epc:if test="creator"><epc:print expr="creator" /></epc:if>
       <epc:if test="!(creator)"><epc:phrase ref="eprint_field_nodata" 
/></epc:if>

... but this doesn't seem to work

(and yes, I've restarted the server..... but that shouldn't make a 
difference for a generate-static)

I'm getting no errors from the xml file, and if I add in a sneaky <hr /> 
them that appears in the re-built page.

How do I avoid rendering these empty tables?
