This page has 3 items that are between parentheses, there is an explanation why they are used this way ?


Each syntax element is described below in more detail.

context_itempath_expression [ AS json_path_name ] [ PASSING { value AS varname } [, ...]]

The input data to query (context_item), the JSON path expression defining the query (path_expression) with an optional name (json_path_name), and an optional PASSING clause, which can provide data 


Why (context_item), (path_expression) and (json_path_name) are inside a parentheses ? This is not usual when explaining any other feature. 

regards
Marcos
