/**
* class Doctrine_Import_XML
*
* Different methods to import a XML schema. The logic behind using two different
* methods is simple. Some people will like the idea of producing Doctrine_Record
* objects directly, which is totally fine. But in fast and growing application,
* table definitions tend to be a little bit more volatile. importArr() can be used
* to output a table definition in a PHP file. This file can then be stored
* independantly from the object itself.
