    <p>Hi Stephan,</p>

    <p>For ZF 2.0, it would be great to have UUID support. Validation and generation (I noted your comment on the Zend_Uuid proposal). Could you updated me on your status? At present, it's becoming unavoidable but to duplicate what your proposal would achieve and I'd prefer to avoid that.</p>

    <p>Note that the CR Team (we're doing a stack of proposal work) is actively reviewing proposals for 1.11 which has a deadline of end of August, and ZF 2.0 is pretty much open as is. I'd be happy to push this proposal along as fast as I can if I you are interesting in persuing this.</p>

    <p>If you're willing to work to work on the generation proposal (trying to contact those authors), please let me know.</p>

    <p>Hi Stephan,</p>

    <p>You can also use Zend_Uuid for validation.</p>

    <ac:macro ac:name="code"><ac:plain-text-body><![CDATA[
    $import = Zend_Uuid::import('ac6773e0-d899-11df-84b3-00112233445');

    <p>In our import function throws an error if it;s not a valid uuid. This check is also byte safe.</p>

    <p>Also the compare function is maybe nice to have in validate.</p>

    <p>In my proposal i now have a ZF 1.10/11 and ZF2 version, maybe you can check if it works for you <ac:emoticon ac:name="wink" /></p>
