Line #394 tests for a truthy $value when setting an attribute. This doesn't allow me to specify an empty attribute. For example, I want to set the attribute "itemscope", a required attributed for HTML5/Schema.org microdata. If I specify:

$item->itemscope = "";

The itemscope attribute is not set on the element as line #397 removes it.
