The XING user property does not render a clickable link. Instead, the user is sent to the regular homepage. There is some bogus comment about mail
adresses, however the XING property works only with the XING profilename anyway.
The link should be change to automatically launch the XING profile.
The Skype user property on the other hand has some rendering issues. The line in the table has a larger height due to an embedded p tag. This should be fixed to make it visually more appealing.
