BaseX error: No namespace declared for 'doc:csv'

问题

Referencing the csv module, how is the following data downloaded?

nicholas@mordor:~/flwor/covid$ 
nicholas@mordor:~/flwor/covid$ basex uri.xq 
Stopped at /home/nicholas/flwor/covid/uri.xq, 3/13:
[XPST0081] No namespace declared for 'doc:csv'.
nicholas@mordor:~/flwor/covid$ 
nicholas@mordor:~/flwor/covid$ cat uri.xq 
xquery version "3.1";

let $csv := doc:csv('http://www.bccdc.ca/Health-Info-Site/Documents/BCCDC_COVID19_Dashboard_Lab_Information.csv') as $data
return $data
nicholas@mordor:~/flwor/covid$

which of the following:

csv:parse csv:serialize csv:doc

is best used to grab this data?

and is there a missing import statement for the namespace?

with powershell:

how to get the column headers for CSV data with Powershell?
