Say I load this file through a DATA attribute of a SELECT element:

<xh:option selected="selected">PASS</xh:option>
</foo>
</xh:select>
Should it say PASS? Is it undefined? Is there a specification which defines
this?
"If a user agent encounters an element it does not recognize, it should
try to render the element's content."

It is unfortunate that they use the word "render", but the intent is to
ignore unknown elements, but to continue processing their child nodes.
So it should say PASS.
(Note that I'm ignoring that you say that you load this file though a
DATA attribute. I don't think it should matter how the markup has come
into existence.)
