 it's not, it should at last return the feature header. See
 
http://www.google.fr/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDoQFjAA&url=ftp%3A%2F%2Fftp.t10.org%2Ft10%2Fdocument.97%2F97-263r0.pdf&ei=LDNDUcbmF8eQhQeG84DgCA&usg=AFQjCNEFP6HJkVddmEJfQ1fCNHPYRTnonA&bvm=bv.43828540,d.ZG4
 (document T10/97-263r0)
 
 I guess the feature header could have a 0 data length, which would break
 out of the loop immediatly.
