Hi
I am new to this group and XML.Actually i am facing one problem in XML
I am validating a XML file using the XML Schema.There is one TAG in the XML
file as 
<NAME>saurabh</NAME> 
When i am validating this file it is doing the validation proprely.The max
length that is allowed in the NAME TAG is 8(as mentioned in the schema). 
If i am trying to validate the XML file with the TAG value as null like 
<NAME></NAME> 
It is not validation it and giving the error as "..<Line 8, Column 44>:
XSD-2021: (Error) Element not completed: 'NAME'...." What i want is that it
should also validate this file even if there is null value for the NAME TAG.

How can we do it?Can we add something in the schema file so that it allows
null value for a particular TAG 
regards 
Saurabh
