Reload Authentic View, Validate XML
The Reload command reloads the Authentic XML data file. This can be useful if the file has been modified outside StyleVision, especially by another user working from another machine.
The Validate XML (F8) command 
checks the validity of the XML file against the associated schema. Whether StyleVision's XSD 1.0 or XSD 1.1 validator is used can be specified in the Properties dialog. Any additional validation requirement that you have entered for individual nodes (Properties sidebar: Additional validation in the Authentic group of properties) is also checked. The result of the validation check is displayed in a pop-up message box.
