What does mobileUrl mean?
The [[mobileUrl]] property is provided for specific situations in which data consumers need to determine whether one of several provided URLs is a dedicated 'mobile site'. To discourage over-use, and reflecting intial usecases, the property is expected only on [[Product]] and [[Offer]], rather than [[Thing]]. The general trend in web technology is towards [responsive design](https://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 [[url]] 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 [[url]] markup to use [[mobileUrl]] for more mobile-oriented pages. The property is intended for the case when items (primarily [[Product]] and [[Offer]]) 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.
