Before in the document one of the rules was no frames. But now, in the mtld.mobi document it says the following:
4.1.3 Use of Frames
[dotMobi] Do not use frames (standard or inline) unless the target client is known to support them
http://pc.mtld.mobi/documents/dotmo...per_Guide3.html
Notice the words "in case the target client is known to support them"
All the latest PDAs and windows mobile (from my treo 700W) are known to show frames now, so the "target client supports them" in this case and my subsequent interpretation now is its ok to use frames. It is just that the current windows mobile does not support the Iframe tag (and Java yet, but thats another issue soon to be resolved i guess )
