functx:max-string

The maximum of a sequence of values, treating them like strings

Description

The functx:max-string function returns the maximum of the values in $strings. It differs from the built-in fn:max function only in treats values of all types like strings. The built-in fn:max function, by contrast, treats untyped and numeric values like numbers (and an error is raised if they are not numbers).
