|Validating XML Documents / Validating XML Documents Against a Schema|
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.
