I'm fine with #1 and #4 but not with the others. It's not clear to me
that normalization-form has no impact on resource identifier escaping
and the current reference to XLink 1.0 is inconsistent with XLink 1.1
and RFC 3987 (the IRI specification). For example, with 

  escape-uri-attributes = no
  normalization-form = NFC

input such as

  <a href='Bjo&#x308;rn' ...

would yield in

  <a href='Bj&#xf6;rn' ...

With 

  escape-uri-attributes = yes
  normalization-form = NFC

however it would yield in, as I understand it,

  <a href='Bjo%CC%88rn' ...

which is not in NFC even though that has been requested. Also note that
RFC 3987 requires the result to be NFC-normalized under some circum-
stances, so I think this needs to be clarified in the draft.
