NEW ISSUE: What is the default value for many and mustSupply on Properti

RAISER: Mark Combellack

TARGET: SCA Assembly Specification

DESCRIPTION:

The specification states that the many and mustSupply booleans are optional for Properties. However, the specification does not define their default values if they are not specified.

(References taken from SCA Assembly Specification Committee Draft 01 with RFC 2119 updates (dated 2008-04-22))

Page 19: lines 376 - 378:

376 many : boolean (0..1) - (optional) whether the property is single-valued (false) or multi

377 valued (true). In the case of a multi-valued property, it is presented to the implementation

378 as a collection of property values.”

Page 30: lines 861 – 865

861 many : boolean (0..1) – (optional) whether the property is single-valued (false) or

862 multi-valued (true). Overrides the many specified for this property on the implementation.

863 The value can only be equal or further restrict, i.e. if the implementation specifies many

864 true, then the component can say false. In the case of a multi-valued property, it is

865 presented to the implementation as a Collection of property values.

Page 30: lines 866 – 868

866 mustSupply : boolean (0..1) - whether the property value must be supplied by the

867 component – when mustSupply="true" the component must supply a value since the

868 implementation has no default value for the property.

Page 42: lines 1346 – 1348

1346 many : boolean (0..1) - whether the property is single-valued (false) or multi-valued

1347 (true). The default is false. In the case of a multi-valued property, it is presented to the

1348 implementation as a collection of property values.

Page 42: lines 1349 - 1354

1349 mustSupply : boolean (0..1) – whether the property value must be supplied by the

1350 component that uses the implementation – when mustSupply="true" the component must

1351 supply a value since the implementation has no default value for the property. A default

1352 property-value should only be supplied when mustSupply="false" (the default setting for

1353 the mustSupply attribute), since the implication of a default value is that it is used only

1354 when a value is not supplied by the using component.

PROPOSAL:

I am presuming that the default value for many is false. Therefore, add the following sentence to the end of the many paragraphs detailed above.

“If many is not specified, then the default value is false.”

(I’m not so sure on this one but…) I am presuming that the default value for mustSupply is true. Therefore, add the following sentence to the end of the mustSupply paragraphs detailed above.

“If mustSupply is not specified, then the default value is true”
