Section 7.2 says:

In case of SRP-ID-number wrapping, the last
   SRP-ID-number before the wrapping MUST be explicitly acknowledged, to
   avoid a situation where SRP-ID-numbers remain unacknowledged after
   the wrap.  This means that the PCC may need to issue two PCUpd
   messages on detecting a wrap.

It should say:

In case of SRP-ID-number wrapping, the last
   SRP-ID-number before the wrapping MUST be explicitly acknowledged, to
   avoid a situation where SRP-ID-numbers remain unacknowledged after
   the wrap.  This means that the PCC may need to issue two PCRpt
   messages on detecting a wrap.

Notes:

incase of srp id wrap, once PCC detects it, PCC needs to issue PCRpt message not PCUpd message.

Section 6.1 says:

Under section 6.1, PCRpt message is defined.
In definition of path,

    Where:
      <path>::= <intended-path>
                [<actual-attribute-list><actual-path>]
                <intended-attribute-list>


And in the same section in 4th last paragraph:

"Note that the intended-attribute-list is optional and
   thus may be omitted.  In this case, the PCE MAY use the values in the
   actual-attribute-list as the requested parameters for the path."

Notes:

The definition of <path> defines that <actual-attribute-list> is optional, whereas down in paragraph it says <intended-attribute-list> is optional.

This creates the conflict between PCRpt message format and the text description of the message.
