Site Column with RichText support

Scenario:
I was suppose to write a site Column with RichText with HTML support.

Solution:
Field tag exposes RichText and RichTextMode properties.

Code:

  <Field ID="{GUIDwithBraces}"
        Name="Details"
        SourceID="http://schemas.microsoft.com/sharepoint/v3"
        StaticName="Details"
        Type="Note"
        RichText="TRUE"
        RichTextMode="FullHtml"
        IsolateStyles="TRUE"
        DisplayName="Details"
        Sortable="FALSE"
        NumLines="15" />
