Type: Technical
Reported by: Upendra Singh <[email protected]>

Section: 6.1

Original Text
-------------
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."

Corrected Text
--------------


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.
