/**
* Validator class.
*
* This class will have several static methods to check if a input string is of
* a certain format.
*
* Most of the definition is reight out of the original RelaxNG schemata for
* OpenDocuments.
*
* We use Regular Expression Functions (Perl-Compatible) aka <i>PCRE</i> in this Validator
* class. Beginning with PHP 4.2.0 these functions are enabled by default. You can disable
* the PCRE functions with --without-pcre-regex. Use --with-pcre-regex=DIR to specify DIR
* where PCRE's include and library files are located, if not using bundled library.
* For older versions you have to configure and compile PHP with --with-pcre-regex[=DIR]
* in order to use these functions.
*
* The windows version of PHP has built in support for this extension. You do not need to
* load any additional extension in order to use these functions.
