A problem of iret instruction description in Intel 64 and IA-32 Architectures Software Developers Manual

I have read the description for iret instruction inhttp://download.intel.com/products/processor/manual/325383.pdf. I think that there is a problem of thedescription.

In page "Vol. 2A 3-545", there is the following text:
#GP(selector)
If a segment selector index is outside its descriptor table limits.
If the return code segment selector RPL is greater than the CPL.
I think that "If the return code segment selector RPL is greater than the CPL." should be "If the return code segment selector RPL is less than the CPL." Or more precisely,"If the return code segment selector RPL isnumericallyless than the CPL."
I don't know where to report this problem. So I post it here.

Thank you for your feedback.
The pseudo code is correct and the text needs to be corrected to reflect the pseudo code.
