Requirements for .mobi web sites

Any web site using a ".mobi" domain must adhere to three "Mandatory Registrant Rules" published by the dotMobi registry:

  1. The response to an HTTP request for the default document on port 80, such as: ​http://Sample.mobi/​
    ​http://www.Sample.mobi/​
    must be a valid XHTML -Mobile Profile document. To determine if a site satisfies this requirement, go to the W3C Markup Validation Service and enter the URL for the domain, both with and without the "www" as shown for "Sample.mobi" above, to validate the default page on the site (do not include a subdirectory or file path). The results from the validation of both URLs should include this: This Page Is Valid -//WAPFORUM//DTD XHTML Mobile 1.0//EN! To determine if a specific web page is in compliance with the XHTML -Mobile Profile, make sure it uses this DOCTYPE: <!DOCTYPE html PUBLIC "-//WAPFORUM//DTD XHTML Mobile 1.0//EN" "http://www.wapforum.org/DTD/xhtml-mobile10.dtd">
    then submit the page to the W3C Markup Validation Service.
  2. To reduce typing on devices with limited keyboard capabilities, sites must allow access using the second level domain (http://Sample.mobi) as well as the third level domain (http://www.Sample.mobi).
  3. Frames should be avoided.

One way to easily provide content that both satisfies these requirements for mobile devices and can also be displayed in traditional web browsers without having to create duplicate files for different devices is using XSL templates.
