Excluding linked stylesheets on CSS validator?

Hello!

When I validate an URI on the CSS Validator, it also validates the linked
stylesheets.

Is there any way to exclude the linked stylesheets from the validation, so
only the styles defined within the page itself are validated?

I guess there is no option to do that, and that the only way would be
removing the <link href="..." rel="stylesheet" /> tags from the HTML source
and then validating this as direct load.
