Scheme Each URI begins with a scheme name that refers to a specification for assigning identifiers within that scheme. As such, the URI syntax is a federated and extensible naming system wherein each scheme's specification may further restrict the syntax and semantics of identifiers using that scheme. Scheme names consist of a sequence of characters beginning with a letter and followed by any combination of letters, digits, plus (""+""), period ("".""), or hyphen (""-""). Although schemes are case- insensitive, the canonical form is lowercase and documents that specify schemes must do so with lowercase letters. An implementation should accept uppercase letters as equivalent to lowercase in scheme names (e.g., allow ""HTTP"" as well as ""http"") for the sake of robustness but should only produce lowercase scheme names for consistency. scheme = ALPHA *( ALPHA / DIGIT / ""+"" / ""-"" / ""."" ) " Bug closed Core (Other) 1.9 Normal wontfix Unreviewed 0 0 0 0 1 0
