/* This file defines an XML parser, with a few kludges to make it
 * useable for HTML. autoSelfClosers defines a set of tag names that
 * are expected to not have a closing tag, and doNotIndent specifies
 * the tags inside of which no indentation should happen (see Config
 * object). These can be disabled by passing the editor an object like
 * {useHTMLKludges: false} as parserConfig option.
