What is XPointer?

X pointer would benefit from offering the option of developed modest feature set, many vendors involved in developing X pointer. Though many tried nobody has set the goal of speed implementation the single complete implementation of x pointer took about two weeks and four known external implementations of FIXptr proposal each took about half a day  compared to the process of x pointer implementations getting four implementations to  try the proposal on a casual basis was so easy and with this no users of x pointer would lose anything, many people has got the doubt that will a sun patent burn x pointer for this question many experts have given the answers Elliott rusty Harold said that “complete rejection of this specification until such time as sun’s patent can be dealt with more reasonably” .Daniel Veillard who led the meetings on the subject x pointer noted that all cannot be chased if it is done there won’t be any progress all the things that are done also will be wasted. It is described as a big problem by Tim bray he says the responsible thing for sun to do would an official declaration that the patent has no standing in respect of x pointer that to an extent it does sun grants an unrestricted free license any one to use it.There is a comment warning regarding W3C development in general “the trend towards larger specifications is not merely inconvenient for developers it can hamper    implementation attempts, harm interoperatability and dampen enthusiasm for W3C’s work by users and developers alike” the XML dev has been discussing about the terns for the patent until Rusty Herold made for the rejection of the specification after that an analysis of the issue was made by Tim bray he described it as a big problem and suggested it would be more responsible for the sun to make declaration.
