Hi Folks, There is a fascinating discussion taking place on the Saxon mailing list. Here is a recap: Ryan McKinley wrote about the difficulties of creating XPath queries to 5 versions of DDMS (DoD Discovery Metadata Specification). He observed that it is difficult because each version of DDMS uses a different namespace, such as: urn:us:mil:ces:metadata:ddms:4 urn:us:mil:ces:metadata:ddms:5 Ryan lamented: “I could create 5 different (but nearly identical) queries for each version.” Michael Kay responded: Versioning of namespaces is nearly always
a mistake, but it's a rather common mistake. |
