Is there a way to add NULL as a coded value in a domain?

[JoanSteinbacher]

I have several coded value domains set up in my geodatabase.  I want to add the value NULL as a Code with the Description "blank".  So if the attribute's value is <Null> it will display the string "blank".  Is this do-able?

I'm thinking the only way you could achieve this affect is if you set the default value to NULL.  You could set it to whatever you wanted actually to get the desired affect.

I don't think it is possible to have the <Null> value (value that displays when an attribute is left blank) set as a domain.  I tried setting it as a domain and it wasn't working.

Hope this helps
