Sorry, I interpreted "request" as "query." Naturaly Mneson can update too. The two primitives are connect two vertices, disconnect two vertices. See also Mntext. (I'm working on Uniformal, the Mneson language that encompasses all these aspects. I can send drafts if wanted.) XQuery cannot update, no. But I'm sure there is a subset of the myriad XLanguages that does. (Note I do not endorse the XML way. Mneson is partly a reaction to its *unnecessary* complexity.)
