Public XSDs

[Adrian Crum]

I was going through the widget-menu.xsd file - intending to update the 
default values to use the new CSS styles. Then I got to thinking that 
publishing the updated xsd file on ofbiz.apache.org/dtds/ would break 
existing installations that use the old CSS styles.

Am I correct? If yes, then is it wise to supply default values in a 
public xsd file?
