I don't think you can use the fallback content as a method of optionally
loading the script tag.
The resource is loaded as part of the DOM, the only way to get around
that is with <noscript>, which would get awkward.
I learned this while exploring <img> content in fallback tags:
<canvas><img src="loaded.png" title="this image tag will always be
loaded" /></canvas>.
This is more typical:
if(!self.Intent)
document.head.appendChild(document.createElement('script')).src='shimaddress.js';
