tel: or wtai: as URL scheme?

Hi all,
the validator seems not to like "tel:0123456" URI schemes
as used on my XHTML MP pages.

Other sites use something like wtai://wp/mc;0123456 (e.g.
Google Local). Looking at WICD Core 1.0 at
http://www.w3.org/2004/CDF/specs/CDR/wp-1/wicd.html ,
both tel: and wtai: are allowed.

Any recommendations from the group regarding URI schemes
for using telephone numbers in mobile XHTML MP pages?
What should be preferred?

Cheers
Herwig
