## Description

The method `DocumentTemplate::addStyleSheet()` has been marked as deprecated.

The property `DocumentTemplate::hasDocheader` has been marked as protected as the property is not evaluated anymore in the core.

## Impact

Calling `DocumentTemplate::addStyleSheet()` will trigger a PHP `E_USER_DEPRECATED` error.

Using the property `DocumentTemplate::hasDocheader` will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations

Instances with third party code directly accessing the method or the property.

## Migration

`DocumentTemplate::addStyleSheet()` can be replaced by using `PageRenderer::addCssFile()`.

The property has no migration available.
