The base method calls Microsoft.VisualStudio.Package.LanguageService.GetFormatFilterList and then searches the list for the extension. Note that Microsoft.VisualStudio.Package.LanguageService.GetFormatFilterList returns a single string: the extensions are separated either by newlines or vertical bars ("|") and the base method can handle either separator.
