But you could still use HTML. Elements with a dash in are reserved for custom elements (that is, a new standardised element will never take that name) so you could do:
<paper-author-list>
<paper-author />
</paper-author-list>
And it would be valid HTML. Then you’d style it with CSS, with paper-author {
display: list-item;
}
And so on.If you distribute the paper as XML with an XSLT transform you need to run something that’ll perform that transform before you can read the paper. No matter whether that transform happens on the server or on the client it’s still an extra complication in the flow of sharing information.
