/**

 * @page using_dfa_for_schema Using DFA for validation of correct XML tag occurrence

 *

 * This page describes how to use DFAs for validating that the XML child tags of an

 * XML parent tag occur in the right order.

 *

 * To validate the occurence of XML tags one need a regular expression that describes

 * which tags can appear how often in what context. For example the regular expression

 * of the global <em>attribute</em> tag in XML Schema is (annotation?, simpleType?).

 * That means the <em>attribute</em> tag can contain an <em>annotation</em> tag followed

 * by a <em>simpleType</em> tag, or just one <em>simpleType</em> tag and even no child

 * tag at all.

 * So the regular expression describes some kind of language and all the various occurrences

 * of the child tags can be seen as words of that language.

 * We can create a DFA now, that accepts all words (and only these words) of that language

 * and whenever we want to check if a sequence of child tags belongs to the language,

 * we test if the sequence passes the DFA successfully.

 *

 * The following example shows how to create the DFA for the regular expression method

 * above.

 *

 * \dotfile GlobalAttribute_diagram.dot

 *

 * At first we need a start state (1), that's the state the DFA is before it

 * starts running. As our regular expression allows that there are no child tags, the

 * start state is an end state as well (marked by the double circle).

 * Now we fetch the first token from the XML file (let's assume it is an <em>annotation</em> tag)

 * and check if there is an edge labled with the tag name leaving the current state of the DFA.

 * If there is no such edge, the input doesn't fullfill the rules of the regular expression,

 * so we throw an error. Otherwise we follow that edge and the DFA is set to the new state (2) the

 * edge points to. Now we fetch the next token from the XML file and do the previous steps again.

 * If there is no further input from the XML file, we check whether the DFA is in an end state and

 * throw an error if not.

 *

 * So the algorithm for checking is quite simple, the whole logic is encoded in the DFA and creating

 * one for a regular expression is sometimes not easy, however the ones for XML Schema are straight

 * forward.
