TYPO3 Core

There are certain parts in DocumentTemplate,
one of the main rendering classes for the Backend,
that are not in use anymore, or can be accessed via
the pageRenderer which DocTemplate uses under
the hood.

Additionally, certain options, like rendering XHTML
or HTML3 in the backend is not needed anymore,
as the whole code is targeted to be HTML5
standardized.

The variables

$inDocStyles
$inDocStyles_TBEstyle

are unified within the main inDocStylesArray.

JScodeLibArray is not in use anymore and deprecated
as well. The method menuTable is not in use
anymore and also deprecated.
