====== Zend_Validate_Array class ======

===== About =====
This class was developed when ZF did not have good Zend_Filter_Input. When Zned_Filter_Input was created (ZF 1.0.0) this class lost some of its benefits but is is still useful for people which want to add end-user custom error messages. You can then use Zend_Translate_* . Also Zend_Validate_* classes are not designed to have end-user friendly error messages (to many of them and to detailed ex. Zend_Validate_EmailAddress).

I have no time to polish this class. Here I mean that it does not confirm ZF codding standards and that some of method names could sound strange. I have created proposal in ZF developer (in archive as there were low interest for this) wiki so any contribution is welcome especially if someone want to polish this class.

:!: **NOTE** - I will be much happier if ZF implemented setUserMessage/getUserMessage method in Zend_Validate_Abstract. But they did not because they said that Zend_Validate is low level and messages are not meant to be passed to users 8-O . Anyway I think they now have some problems. Especially in context of Zend_Form as it is using those low level error messages and displaying them to users :-)

:!: **NOTE** - There is uptodate version in SVN of my project loota [[http://svn2.assembla.com/svn/loota/trunk/Core/lib/ZFext/Validate/]]
