Reusable HTML, does it exist? (Like the Scriptlet)

Hello, I'm investigating how HTML can be componentized and reusable. Remember Microsoft's SCRIPTLET object (TYPE="text/x-scriptlet")? I thought this was a great invention. But other browsers do not support it! I'm not even sure the latest IE will even support it.

I have custom html ui blocks that I want to place many times on a screen. Like custom text fields, custom buttons, and other custom ui elements coded in HTML (that are browser aware). I am familiar with server side solutions (ASP.NET user controls & server controls), but is there any technique/approach not dependent on the server?

Are there any alternatives? New XHTML features, anything?

I believe that your only option is going to be server side which can handle this dynamically for you. Unless you can use some Ajax, not sure on that one.

it is possible, but you have to use XML (import XML → (DOM) → HTML) otherwise you have to parse the markup by regular expressions which will result in a lot of code.
