Section 5 says:

   If the notifier includes the <temp-gruu> element, it MUST populate
   the element with the most recently assigned temporary GRUU that is
   associated with the instance ID and AOR of the registered contact.
   It MUST also populate the element with a "cseq" attribute
   corresponding to the first (oldest) currently active temporary GRUU
   that is associated with the instance ID and AOR of the registered
   contact.  The value of the "cseq" attribute is set to the value of
   the CSeq header field of the REGISTER request that caused that first
   temporary GRUU to be assigned.

It should say:

   If the notifier includes the <temp-gruu> element, it MUST populate
   the element with the most recently assigned temporary GRUU that is
   associated with the instance ID and AOR of the registered contact.
   It MUST also populate the element with a "first-cseq" attribute
   corresponding to the first (oldest) currently active temporary GRUU
   that is associated with the instance ID and AOR of the registered
   contact.  The value of the "first-cseq" attribute is set to the value of
   the CSeq header field of the REGISTER request that caused that first
   temporary GRUU to be assigned.

Notes:

This replaces '"cseq" attribute' with '"first-cseq" attribute.
This is almost a typo, since there is no "cseq" attribute of <temp-gruu>.
Following the text as written would yield an invalid xml document.
