[basex-talk] Computed namespaces: which one is wrong?

Hello all, in 7.6 I used to write code like the following one: <a> {namespace { "" } { "eeeeee" }} </a> it uses to return this as (the expcted) result: <a xmlns="eeeeee"/> In 7.7 the same code snipped returns a runtime exception stating that namespace '' has been declared twice. I assume it's because a default namespace is created under the hood on the root node. Is it? Could I please have any help on this? Thanks a lot, M.
