However, the license "is limited to the creation ... of ... implementations of this specification that (i) include a complete implementation of the current version of this specification ..." I beleive, that if someone implements XSLT processor and claims the full conformance to XSLT 1.0, she automatically admits that the relevant portions of JDK 1.1 were used. This might mean that the implementor DOES PRACTICE the JDK 1.1 specification. Clearly, such form of PRACTICE is not covered by the license cited above, and it might happen, that implementor of XSLT did something not permitted by the owner of the intellectual property. What means "to practice a specification"? Is it allowed to implement a portion of a specification if the owner of that specification explicitly disallows this? I don't know. To get the answer I must ask a lawer, and I will probably need a very good lawer to get an answer, and I will be not surprised if even the good lawer will not be able to give the exact answer. And, by the way, good lawers are very expensive - why should I spend my money to solve this artificially created problem? Too much troubles around a very simple issue. Would not it better just to place all relevant descriptions in the recommendation itself, avoiding potentially dangerous references to the privately-owned specifications? > > Note that Microsoft has implemented format-number, which I doubt it > would have done if its lawyers thought it needed permission from Sun to > do so. > I am not convinced. First, Microsoft can afford legal battles which would surely knock down a smaller company. Second, Microsoft might have the appropriate argeement with SUN, covering the use of technologies owned by SUN. Kind regards, Alexey
