  This is a confusing statement since it did not specify the context.
The original mail was clearly for parsing, not for tree operations. This
is not required for parsing. This is required for tree operations.

  Right ... at parse time. 
  It's not an "attribute"
  If the encoding is not supported parsing will simply fail as required by
the XML spec. "directly" is wrong since libxml may use the iconv library
to do the conversion for encodings which are not supported directly by
libxml2 code.

  Right at parse time. Wrong when editing the tree.
Whatever the encoding of the serialization, any modification or query of the
parsed tree myst use UTF-8.

  True for parsing only.
