A conformance statement is a detailed description, in a specific format (as defined in Part 2 of DICOM) of the DICOM-specific features of a particular product.

Amongst other things, it describes:

• The SOP classes and transfer syntaxes supported
• What "real-world" activity triggers or is triggered by what network operations
• Character sets supported

etc.

Note that the requirement to relate to real-world activity makes it impossible to have a true DICOM confomance statement for a toolkit such as DicomObjects, and this is explained more fully on the DicomObjects_Conformance_Statement page.
