The Oxygen XML Editor Quick Fix support helps you resolve errors that appear in an XML document by offering quick fixes to problems such as missing required attributes or invalid elements. This section explains the quick fix support for XSD, Relax NG, and Schematron validation errors.
To activate this feature, place the caret in the highlighted area of text where a validation
error occurs. If a Quick Fix is available for that particular error, the 
icon is displayed in the stripe on
the left side of the editor. If you click this icon, Oxygen XML Editor displays the list
of available fixes. You can also invoke the quick fix menu by pressing Alt 1 (Command Alt 1 on OS
X) on your
keyboard.
Whenever you make a modification in the XML document or you apply a fix, the list of quick fixes is recomputed to ensure that you always have valid proposals.
