You didn't. What I meant is that I don't think you can do everything
with XSLT 1.0 that you can do now with a subset that does not include
xsl:if (xsl:choose can be implemented in xsl:ifs). For XSLT 2.0, you can
apply predicates on sequences, which I think would suffice to replace
xsl:if, but in XSLT 1.0 you cannot, as far as I can recall.

Of course, in my original question I wasn't clear about what language
features the subset should, and which they should not cover. But I think
it should be able to deal with strings.
