That's perl, not mark-up.

That's java, not mark-up.

This citation contains a statement that the "spaces within a URL; they must be "escaped" by converting them to '+' signs".

>http://webpacity.com/support/documentation/script_var.html

This citation contains a statement that the "For example URL encoding converts all spaces to "+" where as escaping converts a space to %20".  However, it's the website of a testing company, and refers to their own 'Webpacity' script.

| Precisely.  The query part includes '+'.  Not the URL part.  We are only talking about URLs that are persistent identifiers for entity catalogues.  Not queries.

The query is part of the URL.

A quick Google search finds lots of references to using "+" to mean " "
in URLs:

It is a standard practice.
