I have discovered that a significant amount of existing code already
uses upper case A-through-F characters when %-escaping.  I wonder upon
what grounds you recommend the use of lower-case?

In particular we should note that the XQuery 1.0 and XPath 2.0 Functions
and Operators escape-uri() function [1] recommends the use of upper

"To ensure that escaped URIs can be compared using string comparison
functions, this function must always use the upper-case letters A-F."
