What is the grammar for atom:link/@length? Is it 1*DIGIT with no leading or trailing white space? Is it xsd:nonNegativeInteger (which allows a leading "+", leading whitespace, and/or trailing whitespace, as well as negative zero)?
I would like to submit an errata to RFC 4287 saying that the syntax is 1*DIGIT, where DIGIT is any ASCII digit "0".."9", with no leading or trailing whitespace. Any objections? Regards, Brian
