I guess if you're careful you could write a write a file that is both 
valid XML and valid XQuery.  Then you could use a call the 
doc("thix.xml") to access the document, or you could use the (not-yet 
implemented Qexo feature to bind the top-level focus.

I suspect XSLT would work better for you.  You can use XSLT's
"simplified stylesheets".  For example:

<result xsl:version="1.1"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
    <field name="one" value="11"/>
    <field name="two" value="12"/>
    <computed name="hehe" value="{sum(result/field/@value)}"/>
</result>

Running this through Saxon (7.6.5) and specifying the same filename for 
both the input document and teh stylesheet, I get:

<?xml version="1.0" encoding="UTF-8"?><result><field name="one" 
value="11"/><field name="two" value="12"/><computed name="hehe" 
value="23"/></result>
