We also should not forget that XML-DATA was a latecomer to the party

needed for document-oriented XML, and *that*'s what upset the
programmers. The most frequently-quoted objection was "IDs have to start
with a letter? What kind of **** is this? Ours all begin with digits..."

 

None of C++, Java, _javascript_ or Python allow you to start an ID with a digit.
