Um, pretty sure XHTML strict, for example, won't allow arbitrary attributes.
For example, using the 'border' attribute on an img element will break validation.

Any elements or attributes not defined in the corresponding DTD or scheme would need to be removed before the results are sent to a
browser.

This is one reason PIs (processing instructions; <?name target ?>) work well, or else non-HTML/XML markup (e.g. <% %>) that gets
removed before any HTML/XML tools see the text.
