– Setting a field to ReadOnly will cause the field to not display in
the Site Columns page in SharePoint. I’m not even sure if the field is even
there and only hidden.
– If the field does not appear in the Site Coluns page, change the GUID, Name,
and StaticName to something that is unique. If the site collection already has
a field with the same Name or StaticName attribute, it may not be created properly.
User field types:
– Allow only select people (not groups).
UserSelectionScope=”0″ (All people)
UserSelectionScope=”ID-HERE” (Only allow people in a specific Group, where ID-HERE is the group id.)
– Type=”User” (allow only one selection)
Type=”UserMulti” (allow multiple selections)
Rich Text field types:
RichTextMode= HtmlAsXml or FullHtml or Compatible
