In addition, the data structures for the enumerated method have been extended to allow for the specification of parameters that define exactly how that particular colourspace was encoded in the file. For example, the CIELab colourspace, as defined by Rec. ITU-T T.42 specifies six parameters that specify the exact encoding range and offsets of the stored data. To properly interpret a CIELab image, the decoder is required to know this information and apply those parameters to the decoded image data. Enumerated parameters are specified individually for each enumerated colourspace that requires parameters. However, many colourspaces do not require additional parameters, and thus additional parameters are not defined for those colourspaces. For colourspaces that do specify additional parameters, default values may be defined (as for example are done for the definitions of CIELab and CIEJab). If the entire block of additional parameters are not contained within the Colour Specification box, then the default values shall be used; however, if any additional parameter is specified for a particular Colour specification box, then all additional parameters shall be specified for that Colour Specification box.
