Edit a Winword file with Protected Parts in the document

Hi,

I was testing the RichTextEditor First Look in Demos and notice that it doesn't allow us to edit any parts of the document when the same document have specific parts of text locked for edition/change.

If I open the same document in Winword I can add or change text in others parts of the document that are not locked, without Word asking me the password or remove the "restrict editing" settings.

Is there any work around to overcome this issue in RichTextEditor?

PS: I don't want leave here any external links, but if you search for "how to lock specific text in word" in google you will see examples how to lock specific parts or sections of a winword document.
