I see… Instead of immediately executing the query, you are only interested in parsing errors, right?
Sounds reasonable. We could have some more thoughts on how the output of such a function (e.g. xquery:parse) could look like. Instead of returning an error, we could return an element that contains the information that would otherwise be bound to the error variables in a try/catch statement [1]: <error> <code>err:XPTY0004</code> <description>...</description> ... </error> Some other information could be returned if parsing was successful. – You are invited to add some more ideas in the corresponding GitHub issue [2].
