When there is a single-node binding, the context item always has a size of
1 (or may be missing). This is a bit tricky. What does this do:

<xf:repeat ref="1 to 10">
  <xf:output value="position"/>
</xf:repeat>

vs.

<xf:repeat ref="1 to 10">
  <xf:group ref=".">
    <xf:output value="position"/>
  </group>
</xf:repeat>
