I got some error messages today which seem to indicate a problem, either in BaseX or in (my understanding of) the documentation. Since the error messages (in the attached log) suggest contacting you about it, I am doing so. The document at http://www.w3.org/TR/xsd-unicode-blocknames/ includes a table of Unicode block names created by querying a database consisting of XML representations of the various versions of the Unicode Database. Today I noticed that a new version of the Unicode Database was issued in January, and so I downloaded the XML data and added the document to my existing BaseX database of Unicode information. The command seemed to run successfully, but when I ran my old query, I got an error message saying "Data access out of bounds". I installed version 7.2 then, which gave the same error message. Rebuilding the database from scratch allowed me to run the query without any problems, so I don't actually have a problem at the moment. But I'm sending this problem report in the hopes that it may help you diagnose either a problem with dynamic adds to a database or perhaps a problem with the server command language documentation (it's entirely possible that I did something wrong when adding the new document to the database). If there is any information I can provide that would be helpful, please let me know. best, Michael Sperberg-McQueen -- **************************************************************** * C. M.
