[basex-talk] Setting the context item via the native protocol

Howdy --

Right now, I'm aware of two ways to set the context item via the native protocol:

(1) Insert a "declare context item" header into the document

- Disadvantage: Should only work when XQUERY3 is true - Disadvantage: Modifies line/column references for errors received - Disadvantage: Hard to ensure that user-provided XML document will evaluate to itself in XQuery (security risk)

(2) Use the "CS" ["Context Set"] command

- Disadvantage: Requires a database to be open (why?) - Disadvantage: Hard to ensure that user-provided XML document will evaluate to itself in XQuery (security risk)

Is there a better approach?
