If you don't change the active editor and you don't switch to other application, the
schema associated to the current document is parsed and cached by the first
Validate Document action and is reused by the next actions
without re-parsing it. This increases the speed of the validate actions if the schema is
large or is located on a remote server on the Web. To reset the cache and re-parse the
schema you have to use the
Reset Cache and
Validate action. This action will also re-parse the catalogs and reset
the schema used for content completion.
