Wouldn't the equivalent be

<xsl:with-context select="some-node">
    ... stuff happens...
</xsl:with-context>

Using for-each-group gives you a sequence in current-group(); I would think that if you expect a sequence, you might-maybe be better to use xsl:for-each rather than xsl:with-context.  If I understood the original idea, it was a way to be less confusing by not using xsl:for-each in the singleton case.

If we were to allow modes on xsl:with-context, it'd be a way to do mode-based selection.
