Rendering options for ordered lists

[adunning]

It is possible in HTML to specify @type for <ol> to specify the numbering type, as follows:

<ol type="1">
<li>Test</li>
<li>Test</li>
<li>Test</li>
</ol>

I'm assuming that one would need to convert this into TEI using @rend on <list>. For consistency, it might be useful to have preset attributes corresponding to these in TEI Simple.
