1. Comment: 1
2. Implementation Specification Section number: Figure 1, Table 3, wcsCommon.xsd, accompanying text
3. Criticality:  Major
4. Comments/justifications for changes:
ServiceParameters contains a component supportedFormatList. Intended use is, with some extension, to indicated the data formats in which coverages can be requested.
However, this cannot be decided once and for all a priori: If slicing is applied in a GetCoverage request then the dimension of the result will change, and different formats can apply then.
Example: a 3D cube cannot be encoded in JPEG, whereas a 2D GetCoverage slicing can.
Hence, it is recommended to drop this item from the specification.
Should it be kept than there is an item in the specification which cannot be used in the intended meaning and will be confusing at best.
