[TYPO3-RTE] RTE removes span-tags after saving

If the span is removed on save, you may conclude that this is due to 
your proc options (RTE.default.proc) which govern the RTE content 
transformation on the way to the database.

The span tag is removed if it has no attribute.

The class attribute of the span tag may be removed because the class it 
specifies is not allowed. If the class attribute is the only attribute, 
the tag is left with no more attribute, and is removed.

Allowed classes are specified by the RTE.default.proc.allowedClasses 
property.

Therefore, if you are using the Typical default configuration, you 
should add the following to your configuration:

RTE.default.proc.allowedClasses := addToList(red)

Kind regards,
Stanislas
