First of all, from https://en.wikipedia.org/wiki/HTML_attribute#Description
<div span=2>text</div>
and
<div span="2">text</div>
are the same. That is, attributes are pretty much strings. Xexpr thus
follows this, requiring that you always pass a string as an attribute.
To get what you want, you would write
◊div[#:span "2"]{text}
Or this:
◊div[#:span (number->string 2)]{text}
