<br>
I'd prefer to explicitly enumerate the elements we're talking about,<br>
rather than giving rules which risk being interpreted differently by<br>
different people.<br>
For example not all <link>s are automatically downloaded, such as<br>
<link rel=prev>. However I suspect that we'll want all <link>s to<br>
behave the same.<br>
<br>
So the specific list would then be:<br>
<br>
<img><br>
<link><br>
<script><br>
<iframe><br>
<video><br>
<audio><br>
<object><br>
<embed><br>
<source><br>
<input type=image><br>
<br>
<br>
All of these would never attempt to fetch a resource if the src/href<br>
attribute is empty (even if the current baseuri is different from the<br>
document uri). However it would not act as if the attribute was not<br>
set (important for <script>).<br>
<br>
Does that sound right?<br>
