* Callback for `wp_kses_split()` for fixing malformed HTML tags.
*
* This function does a lot of work. It rejects some very malformed things like

* `strip_tags()`!). Otherwise it splits the tag into an element and an attribute
* list.
*
* After the tag is split into an element and an attribute list, it is run
* through another filter which will remove illegal attributes and once that is
* completed, will be returned.

* Removes all attributes, if none are allowed for this element.

* doesn't fall into the list, the attribute will be removed from the tag.
*
* Attributes can be marked as required. If a required attribute is not present,
* KSES will remove all attributes from the tag. As KSES doesn't match opening and

* fallback is to strip all attributes from the tag, instead.
