[Gridftp-wg] unable to resolve reference in documents/GWD-R/GFD-R.020.pdf

[Matt Crawford]

I cannot find the document referred to in the following text in
http://www.ogf.org/documents/GWD-R/GFD-R.020.pdf

FTP Extensions, R. Elz, P. Hethmon (September 2000)
Commands used by GridFTP
    SIZE
Features used by GridFTP
    Restart of a stream mode transfer


Is there an RFC number?  Was this an improper reference to a now- 
vanished internet-draft?
