Should return a summary of the content of the file being accessed. (Called by IPTAccessor.DocumentSummary().) If CanSummarizeDocument() returns false, this method should throw an exception (although the portal should not call it). This method may throw an exception if a summary could not be suggested, but other Get.. methods may still be called. If the file is completely unparsable, then throw an exception in AttachToFile to prevent this method from being called, or throw separate exceptions in the other methods.
