Description: ------------ validateParam expects all values to only contain a-z, 0-9 and dash, which is a huge problem if you add an email address (e.g. foo@bar.com) or a phone number (e.g. +49-170-xxx) Any email (should) contain @ and at least a single dot. Phone numbers can really contain "+" (in the country code). By the way, spaces should be allowed as well (e.g. in a street name). Also, since vcard really is an open format, I am not sure how much sense it makes to "validate" input at all. If appropriate I'd propose to validate in the designated methods - e.g. addTelephone(), addEmail(), addAddress(). Last but not least, another problem is that the error returned is really not returned/thrown outside the class. Instead it is saved in place of the proposed field/value. I am creating a patch for all this now which I will share later today.

Added the patch. Point taken it's a quickfix, but it does the job. Feedback?

Fixed in CVS. Will roll a new release soon.
