Xml

I'm wondering if I am missing something obvious.

I have a list of numbers, possibly including ranges (think of the print page option of a print dialog).

Ideally I'd like to have the final XML output look like this, with page and pageRange in an order.

  <pages>
 <page> 1</page>
   <pageRange><start>3</start><end>6</end></pageRange>
   <page> 34</page>
</pages>

What would I have to put into a schema to allow this?

From what I saw: Sequence with multiple page and page Range allowed doesn't permit alternation. Choice only allows one or the other.

I tried messing with all, but I wasn't getting it to validate properly.

My short term solution is to have a sequence of ranges, and to force single numbers into the range, but it seems potentially cumbersome. So am I missing something?
