And received the warning: "Sort key will have no effect because its
value does not depend on the context item"
The xsl:sort is the first child of xsl:for-each as it iterates through
the items in one group, so, as the warning says the grouping-key will be
the same for each item.
Perhaps you meant to sort the groups, in which case, move the xsl:sort
up a line so it is the first child of xsl:for-each-group.

your for-each-group is selecting Text elements so each group will just
consist of Text elements, so the value-of is taking the string value of
an empty element, which is always the empty string.
