  1. Monolithic Artifact Proposal • Current • Selectivity, i.e. Features, assumes that a unique content unit(s) contains the support for each selection. • Issue • Some existing artifacts are monolithic. • Selectivity needs to be declared • Selectivity defines “switches” for deploying the monolithic artifact • Proposal • Provide the ability for the selection of a Feature to define, and set the value of, a variable, i.e. the selection of a feature sets a variable. • This variable can be used by the content unit that contains the monolithic artifact. <complexType name="FeatureType"> <sequence> <group ref="sdd-dd:DisplayElementGroup" minOccurs="0"/> <element name="Condition" type="sdd-dd:ConditionType" minOccurs="0"/> <element name="SupportedLanguages" type="sdd-dd:SupportedLanguagesType" minOccurs="0"/> <choice maxOccurs="unbounded"> <element name="Feature" type="sdd-dd:NestedFeatureType"/> <element name="ContentElement" type="sdd-dd:ContentElementReferenceType"/> <element name="RequiredFeature" type="sdd-dd:FeatureReferenceType"/> <element name=“Variable" type="DerivedVariableType"/> </choice> <any namespace="##other" processContents="lax" minOccurs="0" maxOccurs="unbounded"/> </sequence> <attribute name="id" type="ID" use="required"/> <anyAttribute namespace="##other" processContents="lax"/> </complexType>
