Deprecation: #100461 - TypoScript option config.xhtmlDoctype 

See forge#100461

Description 

The TypoScript option config.xhtmlDoctype has been marked as deprecated. This is done in order to consolidate TypoScript options, as the option config.doctype is now the default.

Impact 

Having config.xhtmlDoctype set, but not config.doctype will trigger a TypoScript deprecation warning.

Affected installations 

TYPO3 installations having this TypoScript instruction set.

Migration 

If the property config.xhtmlDoctype is set, replace it with config.doctype.
