<blinn> node specification contains a typo

Screenshot of Acrobat Reader 8.1.0 showing the offending page
The <blinn> node specification on page 206 of the 1.4.1 spec PDF has a section "Concepts" which gives the shading equation for the Blinn shader.
This specification has no operator between "max(H . I, 0)" and "<shininess>". I infer that the exponentiation operator is required. This operator needs inserting into the document. Suggest "pow(max(H . I, 0), <shininess>)" for clarity.
(I am reading the PDF on Windows XP. Acrobat Reader version 8.1.0. PNG enclosed with screenshot of the offending page.)
Same as internal issue 874 (https://cvs.khronos.org/bugzilla/show_bug.cgi?id=874).
