Thanks, the note is indeed really useful. For all the following 
statements, do you think it is possible to indicate a suitable reference?
     *  "&" is the only primary separator for name-value pairs, but some 
server-side languages also treat ";" as a separator.
     * name-value pairs with invalid percent-encoding should be ignored, 
but some server-side languages silently mask such errors.
     * The "+" character should not be treated specially, but some 
server-side languages replace it with a space (" ") character.
     * Multiple occurrences of the same name must be preserved, but some 
server-side languages only preserve the last occurrence.

Best regards.
