Thanks Mike,

Dave's mention of xsl:number also helped allot! I think this is the final
solutions for the situation I have

Thanks again to everyone for the help!

This gives me a variable that tells me how many cautions are preceding

In XPath 2.0,

count(preceding::caution intersect ancestor::chapter//caution)

In 1.0, you can simulate the intersect operator using the equivalence

A intersect B ==> A[count(.|B) = count(B)]

But you might be better off using 

<xsl:number count="caution" level="any" from="chapter"/>
