SharePoint Fields – AddingFieldAsXML strange?

Hi,

I was bit happy after knowing that we can also add FieldAsXml in SharePoint but when I came to know something strange while using this method then that made me a puzzle ..

what basically this all about is :

when we add any field using this method then SharePoint just forgets to set Internal Name of the Field ,

Bil Simser has come up with a work around which makes things OK

I also heard somewhere that this issue is still there with SharePoint 2010 APIs .. 

I would surely like to hands on it using SP2010 as soon as I touches SP 2010 (heavy Infrastructure ;)) environment
