How to ensure my doctype is XHTML 1.0 Strict

While working on an XHTML 1.0 Strict page, I discovered that iframe was deprecated. I've done some research, and replaced it with an object tag.

<object id="gmap" type="text/html" data="https://maps.google.ca/maps/ms?msa=0&amp;msid=216725582357492079329.0004cf99c633289e8b190&amp;hl=en&amp;ie=UTF8&amp;t=m&amp;ll=34.870479,-40.172607&amp;spn=34.201734,120.673828&amp;output=embed"></object>

It validated, but as HTML 4.0 transitional. How do I validate it as XHTML 1.0 Strict?

The W3C validator does not validate the content embedded in an iframe or object tag. If you want to know how to make it XHTML 1.0 Strict, start with a valid XHTML 1.0 Strict document, such as: 

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
    <title>Example</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
</head>
<body>
    <div><object data="http://example.com"></object></div>
</body>
</html>

then add your markup without invalidating it.
