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. -- Graydon Saunders | graydonish@xxxxxxxxx ^fs oferiode, pisses swa mfg. -- Deor ("That passed, so may this.")
