So, contrary to what you said about namespaces not being a good 
solution for introducing new experimental features, it would actually 
be simpler to introduce <caption> for other elements than <table> via a 
real/prefixed namespace. For example a transitional namespace for new 
HTML5 features. The following already works.:

<figure><t:caption></t:caption></figure>

As time goes, and old user agents fades out, one could drop the prefix.
