SRU and SRW should remain as much as possible identical. There is no need to make a distinction between SRU and SRW because in SRU one can do the same as in SRW by means of XSL plus Javascript. A very simple test-portal (with a lot of bugs) based on this concept can be found at: http://redbelly.kb.nl/coop/tel/teldbs.xml
