A Variant value.  

object.DefaultValue [= value]

The DefaultValue Property syntax has these parts:

McDBAttributeType objects of any Type except mcdbNodeAtb may be associated with a default value for attributes not explicitly set on a particular McDBNode instance.

Error	Value	Description
E_INVALIDARG	&H80070057	The value being assigned as the Default Value is incompatible with Type.
E_UNEXPECTED	&H8001FFFF	A framework error occurred while accessing the name.
E_ACCESSDENIED	&H80070005	The McDBDatabase.LoggedUser does not have McDBRightsOwner.AttributeTypeAdminRight privileges.
E_NOTIMPL	&H80004001	Type is mcdbOther, and its Default Value cannot be manipulated or represented by McDBLib.

An existing default value is cleared by assigning an empty variant to this property.
