Syntax Rules

From XBRLWiki

• Public elements MUST have two custom attributes: @model:creationDate and @model:modificationDate.
• Language specific information MUST be expressed through label relationships.
• Concepts MUST use 2.1 labels.
• Concepts represented by xlink resources MUST use generic labels.
• Label relationships MUST be placed in an ELR using the default role http://www.xbrl.org/2003/role/link
• 2.1 labels MUST use http://www.xbrl.org/2003/role/label as their role for their standard label.
• Generic labels MUST use http://www.xbrl.org/2008/role/label as their role for their standard label.
• 2.1 labels MUST use http://www.xbrl.org/2003/role/verboseLabel as their role for their definition.
• Generic labels MUST use http://www.xbrl.org/2008/role/verboseLabel as their role for their definition.
• 2.1 labels MUST use http://www.xbrl.org/2003/role/documentation as their role for legal references.
• Generic labels MUST use http://www.xbrl.org/2008/role/documentation as their role for legal references.
• Labels MUST be separated in linkbases according to their language used.

Note:

Current references are described in plain English; as a consequence, labels are a better solution than reference linkbases. In the future, a structured approach for legal references could be undertaken.
