Xattr Metadata - Mandatory?

[Gordan Bobic <gordan@xxxxxxxxxx>]

Is metadata mandatory on all files under AFR? The reason I ask is 
because I seem to have a lot of files in my replicated directories that 
don't have the said metadata. This includes newly created files that 
seem to replicated between the nodes correctly. Is this normal? Nothing 
appears in the logs when creating these metadataless files.
