Utilities for determining whether characters belong to character classes defined

by the XML specs.

## Organization

It used to be that the library was contained in a single file and you could just

import/require/what-have-you the `xmlchars` module. However, that setup did not

work well for people who cared about code optimization. Importing `xmlchars`

meant importing *all* of the library and because of the way the code was

generated there was no way to shake the resulting code tree.

Different modules cover different standards. At the time this documentation was

last updated, we had:

* `xmlchars/xml/1.0/ed5` which covers XML 1.0 edition 5.

* `xmlchars/xml/1.0/ed4` which covers XML 1.0 edition 4.

* `xmlchars/xml/1.1/ed2` which covers XML 1.0 edition 2.

* `xmlchars/xmlns/1.0/ed3` which covers XML Namespaces 1.0 edition 3.

## Features

The "things" each module contains can be categorized as follows:

1. "Fragments": these are parts and pieces of regular expressions that

correspond to the productions defined in the standard that the module

covers. You'd use these to *build regular expressions*.

2. Regular expressions that correspond to the productions defined in the

standard that the module covers.

3. Lists: these are arrays of characters that correspond to the productions.

4. Functions that test code points to verify whether they fit a production.
