It is not about validation but about generation rules, if you can adapt 
something along the lines of

"The formal grammar describe what producers of media fragment should 
output. It is not taking into account possible percent-encoding that are 
valid according to rfc3896. The grammar is not a specification on how a 
media fragment should be parsed, See section 5.1 for the Parsing rules..."
