I didn't quite get the last sentence. Anyhow, most, if not all processors, evaluate variable only when they're needed, so if you don't use $config-top anywhere, the document names.xml is not fetched and read into a source tree. Also, processors cache the documents for the duration of the transformation (or life-span of e.g. Transformer object), so if it's used in multiple locations in your stylesheet, processed only once.
