Description
The functx:sort-case-insensitive function sorts a sequence of values or nodes without regard to whether they are upper or lower-case. Normally, using most collations, all upper-case letters are sorted before all lower-case letters, so "Z" would come before "a". It returns the items in their original capitalization.
