AIUI semi-colons (and equals signs) are actually escaped when inserted  
in the DB so you can theoretically use them. (They're escaped as ;;;  
and ===, oddly.)

Node and segment tags are stored in the db as a single "tags" column  
in the relevant table, so the ; and = form part of the encoding.

Ways are stored a bit more sanely - a whole nother table with way id,  
key and value tags - so the issue doesn't arise.
