Hello,

this is a heads-up for a pitfall (that at least I have fallen into several times now...)

Is there a technique or pattern I could employ (maybe utilizing the @as attribute somehow?)

Firstly, avoid creating temporary trees where you don't need them. Whenever you find yourself using xsl:variable with content, ask yourself whether you shouldn't be using the @select attribute instead.


Secondly, always use the @as attribute to declare the type of the variable you think you are creating. When you declare your types, the compiler can tell you about your mistakes.
