What's the standard for non-standard extensions?

I'm generating pages in which I want to store meta information of
interest to my HTML editing tools and to some of my server applications.

I currently do something like:

<!-- metainfo --> html code <!- /metainfo -->

That obviously works, but is it necessary?

Is it legit for me to do something like this?

<UImetainfo> html code </UImetainfo>

That simplifies my parsing code, makes other tools available to
me, etc. But of course it's non-standard. Also, these aren't
extensions that I would anticipate being of any use to anyone
