Try casting each numerical argument to xs:positiveInteger:

<xsl:sequence select="f:iter($count + 1)" />

<xsl:sequence select="f:iter($count + xs:positiveInteger(1))" />

(also when invoking f:iter outside the recursion).

What is the rationale for this? After all, if I add one (1) to any positiveInteger the result must be a positiveInteger.

Maybe the XSLT processor isn't smart enough. It just seems to adhere to the rule "positiveInteger + integer = integer". I'm not sure whether it's worth the while to make the processor look at the values rather than just at the types before applying implicit typecasts.
