Metacharacter in my understanding of ‘meta’ would mean a character used to represent a character. That meaning seems to fit with its use in regex. It does not fit with XML.

The regular expression metacharacters are:
\ ^ $ . [ ] | ( ) * + ? { }
They are called metacharacters because they have special meanings.
XML has five characters with special meanings:
< > & " '
I searched the XML specification for the word "metacharacter". There are zero occurrences.
Why doesn't the XML specification use the word "metacharacter"?
