It's a good idea with XSLT 2.0 to declare the types of your variables. Doing this makes it less likely you will make such errors, and more likely that when you do make errors, you will get good diagnostics. In this case the problem is that <xsl:variable name="maxloads"> is constructing a document node, so max($maxloads) is converting the string-value of that document node to a number, which fails. Declare maxloads as a sequence of integers, and all will be well.
