The Schema Aware preferences panel is opened from menu .
When opening a document in Author, white spaces can be normalized or removed in order to obtain a more compact display. The reverse process takes place when saving the document in the Author. By default this algorithm is controlled by the CSS display property.
If this option is checked, then this process will be schema aware so the algorithm will take into account if the element is declared as element-only or mixed. It will also take into account options Preserve space elements, Default space elements, Mixed content elements from option page
If checked, even if an element is declared in the schema as being mixed but it has a blocks-only content (as specified by the CSS property display of its children), it will be treated as being element-only.
Editing in Author is schema driven.
Controls the behavior for deleting element tags using delete or backspace keys. Available options:
If checked and the result of the delete action is invalid, the action will not be performed.
Controls the behavior for paste and drag and drop actions. Available options:
If checked and the result of the paste or drop action is invalid, the action will not be performed.
Controls the behavior that takes place when typing. Available options:
If the typed character cannot be inserted at element from the caret position then a sibling element that can accept it will be searched for. If the sibling element can accept the content, then a new element with the same name as the sibling is created in which the content will be inserted.
If checked and the result of the typing action is invalid, the action will not be performed.
Controls the behavior that takes place when inserting elements using content completion. Available options:
If checked, when the Delete Element Tags action will result in an invalid content, a warning message will be displayed in which the user is asked if the operation should continue.
If checked, when the Join Elements action will result in an invalid content, a warning message will be displayed in which the user is asked if the operation should continue.
Convert external content on paste
If checked, Oxygen XML Author preserves the formatting style when you paste content copied from external applications (like web browsers or Office-like applications). This option is enabled by default and applies only to the major document type frameworks (DocBook, DITA, TEI, XHTML) and to those customized to support the content conversion on paste.
If the Schema Aware Editing is On or Custom all actions that can generate invalid content will be forwarded first toward AuthorSchemaAwareEditingHandler.
