Semicolons can be replaced with ampersands; for convenience, and all the URL can be reduced to its query string component (including the question mark). All arguments are optional:

! Argument
|-
| {{Code|lang}}
| A language code, followed by an optional language variant. If no language is specified, the system’s default will be chosen. Examples: {{Code|de}}, {{Code|en-US}}.
|-
| {{Code|strength}}
| Level of difference considered significant in comparisons. Four strengths are supported: {{Code|primary}}, {{Code|secondary}}, {{Code|tertiary}}, and {{Code|identical}}. For example, in German, "Ä" and "A" are considered primary differences, "Ä" and "ä" are secondarydifferences, "Ä" and "A[http://www.fileformat.info/info/unicode/char/308/index.htm &#x308;]" are tertiarydifferences, and "A" and "A" are identical.
|-
| {{Code|decomposition}}
| Defines how composed characters are handled. Three decompositions are supported: {{Code|none}}, {{Code|standard}}, and {{Code|full}}. More details are found in the [http://docs.oracle.com/javase/7/docs/api/java/text/Collator.html JavaDoc] of the JDK.
