RE:  Postel's law
The issue isn't whether they are bugs in the generator. The question is
whether an aggregator should [for example] try each of the heuristics

error message because the Ziff Davis Microsoft-Watch or National
Geographic RSS feed doesn't specify the correct encoding in the XML
declaration.
