It supports the content model restrictions, which are there to avoid authors making mistakes that harm accessibility (amongst other things). Reasons for content model restrictions are discussed in more detail in the introduction to the spec: http://whatwg.org/html#restrictions-on-content-models-and-on-attribute-values If there are specific use cases that can't be done given the current restrictions, please let me know; we can definitely consider relaxing some of the restrictions. (It's very hard to tighten restrictions, but comparatively easy to relax them, which is why we start them on the strict side rather than on the relaxed side.) So far, all the use cases that people have brought up for things that can't be done within the current restrictions also happen to be things that canvas is actually really bad at doing at all. There's another non-normative section that goes into more detail about these kinds of things: http://whatwg.org/html#best-practices -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
