Appendix F.1 of the XML specs presents examples about how to automatically 
detect the encoding of an entity from the first characters of an XML 
encoding declaration without a byte order mark.  These examples include 
UTF-16BE and UTF-16LE. However, section 4.3.3 says that entities encoded in 
UTF-16 MUST begin with a byte order mark.

In the light of the examples it seems that the intention of the specs is to 
demand a UTF-16 byte order mark only when no XML declaration is used.  Is 
this interpretation of the specs correct?

If the answer is "yes", I would suggest to start the second paragraph of 
sect. 4.4.3 with: "In the absence of a text declaration (or an XML 
declaration respectively) entities encoded in UTF-16 MUST ..."

If the answer is "no", I would suggest to remove the two incriminated 
examples from Appendix F.1 and to add an appropriate warning.
