hi,
I have created a simply form with an input like this:

$name = new Zend_Form_Element_Text('name');
$name->setLabel('Nome')
->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->addValidator('NotEmpty');

do you know why my input is not valid w3c?
my output-> <input type="text" name="name" id="name" value="">
zend guide output-> <input type="text" name="name" id="name" value="" />

I have to configure something?
Thanks

In your bootstrap, you need to call something like

The last line tells helpers whether to produce HTML or XHTML markup.

You need to set the appropriate XHTML doctype to produce tags that end with />
