mobileUrl property
//en.wikipedia.org/wiki/Responsive_web_design) in which content can be
flexibly adapted to a wide range of browsing environments. Pages and
sites referenced with the long-established Schemaurl property should
ideally also be usable on a wide variety of devices, including mobile
phones. In most cases, it would be pointless and counter productive to
attempt to update all Schemaurl markup to use SchemamobileUrl for
more mobile-oriented pages. The property is intended for the case when
items (primarily SchemaProduct and SchemaOffer) have extra URLs
hosted on an additional "mobile site" alongside the main one. It should
not be taken as an endorsement of this publication style.
