While in many cases that is sane advice, in this particular case we know that 
RFC 5545 has issues in just this area that are unresolved, likely as a result 
of rampant "committeeitis" where instead of coming to a decision, everyone 
managed to create enough wiggle room for their particular approach, resulting 
in lack of interoperability and reliability for the user.

The solution we've now reached for Kolab avoids those shortcomings, and also 
has the advantage of not requiring to rewrite everything.
