XdmValue for vectors

[akond]

At the moment (sp/->xdmvalue [1 2 3]) throws

Execution error (IllegalArgumentException) at sigel.protocols/eval10142$fn (protocols.clj:64). No matching ctor found for class net.sf.saxon.s9api.XdmAtomicValue

which is weird.

But if I do

(extend-protocol sp/XMLValue
  PersistentVector
  (->xdmvalue [xdmvalue]
    (XdmValue/makeSequence xdmvalue)))

(sp/->xdmvalue [1 2 3]) works fine

=> #object [net.sf.saxon.s9api.XdmValue 0x30e4991a "1\n2\n3"]
