|Data Type||string, between 1 and 128 characters in length.|

|Parent Node||<Field> Node (/SubscriptionClass/Schema)|
Field names must conform to SQL Server identifier naming conventions. For more information about SQL Server identifier naming conventions, see "Using Identifiers" in SQL Server Books Online.
Important You cannot name a subscription field Created, Enabled, SubscriberId, SubscriptionId, or Updated. Notification Services already uses these field names internally.
If you update a <FieldName> element, NSControl Update re-creates the subscription class to which it corresponds. A new subscription table is created, and the existing subscription table is renamed to SubscriptionTableNameOld. Existing subscription table indexes are left unchanged. If you want to transfer data between the old and new subscription tables, it must be done manually.
