How big the table becomes is not important (within the limits of your system's RAM), what is important is the number of unique values between which you will have to choose. If there will be a large number of them, you will have to define a protocol (algorithm) for how the values you do have will be transformed into the values you want. Start with that, and the solution will follow.

If you mean that you have an XML document that maps the values you have to the values you want, then you will want to use the document() function to access it from the XSLT file. You can then use XPath to get the values you need from it.
