It is sometimes useful to specify lists of IDs. To do that, you'll generally need a separator character. It follows that either you'd have to disallow this separator character in IDs, or you have to come up with some escaping mechanism for it. Escaping rules tend to make parsing harder and are often misunderstood, so it's usually better to use a separator character. White space is generally a good choice for that, because considering white space part of identifiers often conflicts with other assumptions about white space, e.g. Is id=' x ' the same as id='x'? Is id='x y' the same as id='x y'? Is id='x y' the same as id='x y'? These questions immediately go away if you disallow white space, and you are then free to use white space for other purpose, as above. -- Björn Höhrmann · mailto:[email protected] · http://bjoern.hoehrmann.de Am Badedeich 7 · Telefon: +49(0)160/4415681 · http://www.bjoernsworld.de 25899 Dagebüll · PGP Pub.
