Re:  Recursive function referencing an XML file
I think it's probably cleanest if all the inputs to a function are explicit in the parameters you pass. So pass the root node of the library XML document as a parameter, rather than calling doc() from within the function. It probably won't make much difference to performance (though performance depends on the product you are using), but it feels right in terms of making your code modular and reusable.

This is more of a programming technique question than a how to.

I'll be creating a recursive function in XSLT that will manipulate a tokenized string (on spaces), capitalize initial letter in each word and lower case the rest of the word. An issue arises for product names and acronyms, as the way they are spelt is quite specific. So I'll create a library XML file that will contain the correct spelling for these strings and do a check on each string.

So my question is,

What is the best method to call the library XML file? As a parameter into the function (placing the content of the library into a variable that is placed into the function), a straight<value-of select="doc('file:///pathto/library.xml')..." /> each time the function is called, or does it really matter as it might make no difference or discernable difference? (I'll be parsing 400+ files all less than 30k.)

Just trying to find the best method someone with a programming background and education (read post secondary education in computer science) would use.
