I've found very few use cases that it doesn't cover, though XQuery windowing
offers a lot of options that xsl:for-each-group doesn't, and perhaps they're
useful to someone... Such as starting a new group whenever @x on the current
item is less than @x on the previous item. Sometimes you can handle these by
binding a variable to the items that match the condition, and then using this
variable in your group-starting pattern.
