That's what I was trying to suggest -- not XSLT, but not just script
either.

But your reply, which is echoed in the spec., confuses me.  When I
point my browser at an XML document with an <?xml-stylesheet. . .?>
PI, e.g. [1], in what sense does anything "alter the underlying DOM"?

The XML DOM is left alone, an new HTML DOM is built, and rendered. 

XSLT is spec'd to produce a new, distinct result tree, certainly not
to modify its input. . .
