Where is "XML Schema" description coming from?

May 5, 2009 at 4:59 PM
On the SharePoint Tips Utility Pack, Lists Management,  Change Field Settings, where is the application grabbing the "XML Schema" from for a selected field in a list?

I was changing some fields to be visibile/invisible on the NewForm.aspx for the Help Desk SharePoint application template (Fab 40) and somehow the field definition showing on the Utility Pack got out of synch with the schema.xml.

Thanks.
