Page title is an imperative part of each page. Each page should contain page title as first element.
Page should be start from tag [h1]…[/h1]. Body of this tag should not contain other tags as HTML presentation. If user type any tags in visual mode, they should be changed to alternate materials (for example, opened tag should be changed to their HTML code with ampersand).
All attributes for titles should be blocked in editor mode.
If user switch to HTML mode and type tags in the body of first tag [h1]...[/h1] in the document, after switching to visual mode, corresponding tags should be changed to their HTML codes and be presented as simple text (not HTML).
Drag and Dropping of images, links, tables and other objects, except formatted text, should be blocked. DEKI should generate alert message (“You cannot drag same objects to page title. Your operation was ignored.” - OK) and make undo of this operation (move object to old place).
For new page if page title is absent, before saving DEKI should generate unique page title name (default name of page + individual unique number).
If user edit already existed page and page title is absent to moment of page saving, DEKI should get old name of this page.
NAV pane should display title from first tag [h1]...[/h1] from the page.
