Preserve the place of annotation meta tags; adds information for the
users about annotation and, if necessary, annotation range extension.
The messages and individual handling of annotations for the annotation
range can be defined by the extensions: see I0b58a418 for an example
of how that can look like.
The structure of this patch closely follows the one from I104e7abbd
(handling of <noinclude> et al.).
