cubicweb #1894008 hook to check RichString attributes on entity modification [open]

when an entity that has a RichString attribute is saved, it would be nice to run some checks.

For example, if the format is ReST, the hook should check that the markup can be parsed without error and can be turned into valid (x)html.
