[Commentor] LC-399 Zev Blut [Comment] 2.2 Input Discusses the potential lack of back button support, but in section 1.4 the default device supports XHTML- Basic. Is it not reasonable that if the default is assuming XHTML-Basic then the target default handsets have back buttons? [Working Group decision] The "back button" is not mandated by any of the specifications that defines the default delivery context, and in particular, there doesn't seem to be any evidence that any device supporting XHTML-basic would feature a back button. As such, we have kept our text regarding the back button as is. [Commentor reply]
