< Metadata >
< Fields >

Displayname = "$ Resources: Core, objectiv_schema_mwsidcam1_c24 ;"
Defaultview = "True" Setuppath = "Pages \ viewpage. aspx"
Imageurl = "/_ Layouts/images/generic.png" URL = "Allitems. aspx" >

< Viewfields >
< Fieldref Name = "Docicon" />
< Fieldref Name = "Attachments" />
< Fieldref Name = "Linktitle" />
< Fieldref Name = "Favoritecolor" />
</ Viewfields >
