- In a list of rules for queries, the vali can be strings or numbers, or the following special forms:
-
True "true"False "false"{e1,e2,…} e1, e2, …
- In URLBuild [assoc], the Association assoc can contain the following elements:
-
"Scheme" URL scheme"User" user information"Domain" domain name or host"Port" port number (as an integer)"Path" path list or string"Query" query string or list of parameter-value pairs"Fragment" fragment specification (given after #)
- If queries are specified both in assoc and with a list of rules, the queries are concatenated.
