W1206 XML comment on '%s' has cref attribute '%s' that could not be resolved (Object Pascal)
This warning message occurs when the XML has a cref attribute that cannot be resolved.
This is a warning in XML documentation processing. The XML is well formed, but the comment's meaning is questionable. XML cref references follow the .NET style. See http://msdn2.microsoft.com/en-us/library/acd0tfbe.aspx for more details. A documentation warning does not prevent building.
