....axes of a newly inserted document node. To delete a node, however, it is su#cient to remove its descriptor entry from accel . 4.1 Node Descriptor Indexing Node descriptors are elements of a 5 dimensional space. Domains of such dimensionality have been found to be efficiently supported by R trees [2]. Our experiments indeed indicate that XPath step evaluation with the help of R trees performs well (Section 6) Our approach to model document regions via query windows is, of course, directly tailored to be supported by a multi dimensional index structure like the R tree [10] Rtrees are well ....
