Formatted message: <a href="http://www.t10.org/cgi-bin/ac.pl?t=r&f=r1504212_f.htm">HTML-formatted message</a>

When I click http://www.t10.org/cgi-bin/ac.pl?t=f&f=spc2r20.pdf to fill
shows up "Resquested URL not found". However, I found the doc at other site.
How about the other questions I made. Am I in a right way?
thanks Frederick
