RE: how to evaluate a dyna generated variable?

This isn't a good way to tackle this requirement.

exsl:evaluate() does say that all the variables are accessible, but you
might find implementations that aren't conformant with this; it's a
heavy overhead for processor to have to maintain so much context at
run-time.

Better to do it in pure XSLT. Rather than declaring several variables
with semantics hidden in the choice of variable names, use the power of
XML to declare a composite (tree-structured) variable, and access it's
components using path expressions. Unfortunately you will also need the
node-set extension.

<xsl:variable name="participants">
  <p nr="1">Absolute Relation</p>
  <p nr="2">Relative Relation</p>
</xsl:variable>

<xsl:value-of select="xx:node-set($participants)/p[@nr=$type]"/>
