This fixes WCAG 2.0 compliance because we were already using HTML5 markup.
The strict XML headers setting never worked for production servers, developers
used browser validators for compliance testing. XHTML 5 option is relatively
similar to this obsolete option, but still it can not be used on production servers.
XHTML Strict 1.x was a standardised dead end, HTML5 is the new de-facto-standard
supported by all major browsers including latest versions of IE.
Please note nothing changes in our coding style because HTML5 is a superset of
several previous standards, it is recommended to use only features that are
already implemented in all our supported browsers.
If the string passed to get_string is empty, say that. Don't say that it
contains illegal characters.
When relying on the __call magic in plugin_renderer_base, when the
method cannot be found, include the right class name in the error
message.

Please note all plugin references from core should use callbacks, it is not ok to use capabilities or links to plugins because they may not be present in customised installs.
