Usage

• {{NAMESPACEID}} → 10
• {{NAMESPACEID|}} → 0 (Article namespace)
• {{NAMESPACEID|{{ns:0}}}} → 0 (Article namespace)
• {{NAMESPACEID|Talk}} → 1

Namespace aliases are accepted, too:

• {{NAMESPACEID|Image}} → 6
• {{NAMESPACEID|File}} → 6
• {{NAMESPACEID|WP}} → {{#invoke:Error|error|Invalid namespace in {{NAMESPACEID}}|tag=}}
• {{NAMESPACEID|Project}} → 4
• {{NAMESPACEID|Wikipedia}} → {{#invoke:Error|error|Invalid namespace in {{NAMESPACEID}}|tag=}}

Invalid input returns an error, which can be caught with the #iferror parser function:

• {{NAMESPACEID|Foo}} → {{#invoke:Error|error|Invalid namespace in {{NAMESPACEID}}|tag=}}
