Use Existing Classification Types

Hi,

I am looking to use Visual Studio existing classification types that already have associated "Fonts and Colors" options. For example, the "XML Name" item. This way, when the user changes the "XML Name" color, or the whole theme, my classification coloring will be updated also.

What name should I pass into "IClassificationTypeRegistryService.GetClassificationType" to get the "XML Name" classification type?
