Minute Error in the following Document

Hi,
I m going through the documentation of OROCOS
Sir, i found some mistake in it at the following link
http://people.mech.kuleuven.be/~psoetens/orocos/doc/api/html/classORO__Geometry_1_1Frame.html

particularly  in the DH-convention documentation it is written as
     //     a(i-1)     = distance from Z(i-1) to Z(i) along X(i-1)
     //     alpha(i-1) = angle between Z(i-1) to Z(i) along X(i-1)
     //     d(i)       = distance from X(i-1) to X(i) along Z(i)
     //     theta(i)   = angle between X(i-1) to X(i) along X(i)

I think it will be more clear if it will be written as

     //     a(i-1)     = distance from Z(i-1) to Z(i) along X(i-1)
     //     alpha(i-1) = angle between Z(i-1) to Z(i) about X(i-1)
     //     d(i)       = distance from X(i-1) to X(i) along Z(i)
     //     theta(i)   = angle between X(i-1) to X(i) about X(i)

thanks
