MARTE — NFP: value syntax

[NFP: value syntax] It may be useful to have a shorter (graphical) notation for NFP types including the value and unit slots only, e.g., ‘(55, kHz)’, or still ’55 kHz’, instead of the notation ‘(55, -, kHz, max, -, est, -)’ with all the qualifiers. This will enhance the graphical models readability. While this feature may be only a tool-specific mechanism, which could propose a graphical view (short notation) of the repository notation (full notation), it would be useful to standardize this notation in the MARTE spec.

We include this syntax (value-unit) only as a tool-specific feature to show NFP values in graphical models. This means that the syntax defined in VSL is still valid for NFP values (tuple notation). The reason is that the model repository needs to keep all the required NFP value information (value, unit, plus other qualifiers).
