Capability and Requirement Namespaces base class.
This class is the common class shared by all OSGi defined namespaces. It defines the names for the common attributes and directives for the OSGi specified namespaces.
The OSGi Alliance reserves the right to extend the set of directives and attributes which have specified semantics for all of the specified namespaces.
The values associated with these keys are of type String, unless otherwise indicated.

- Field Detail
  - CAPABILITY_USES_DIRECTIVE
```
public static final String CAPABILITY_USES_DIRECTIVE
```
    The capability directive used to specify the comma separated list of package names used by a capability.
    
    See Also:
    
    Constant Field Values
  - CAPABILITY_EFFECTIVE_DIRECTIVE
```
public static final String CAPABILITY_EFFECTIVE_DIRECTIVE
```
    The capability directive used to specify the effective time for the capability. The default value is resolve.
    
    See Also:
    
    resolve, active, Constant Field Values
  - REQUIREMENT_FILTER_DIRECTIVE
```
public static final String REQUIREMENT_FILTER_DIRECTIVE
```
    The requirement directive used to specify a capability filter. This filter is used to match against a capability's attributes.
    
    See Also:
    
    Constant Field Values
  - REQUIREMENT_RESOLUTION_DIRECTIVE
```
public static final String REQUIREMENT_RESOLUTION_DIRECTIVE
```
    The requirement directive used to specify the resolution type for a requirement. The default value is mandatory .
    
    See Also:
    
    mandatory, optional, Constant Field Values
  - RESOLUTION_MANDATORY
```
public static final String RESOLUTION_MANDATORY
```
    The directive value identifying a mandatory requirement resolution type. A mandatory resolution type indicates that the requirement must be resolved when the resource is resolved. If such a requirement cannot be resolved, the resource fails to resolve.
    
    See Also:
    
    REQUIREMENT_RESOLUTION_DIRECTIVE, Constant Field Values
  - RESOLUTION_OPTIONAL
```
public static final String RESOLUTION_OPTIONAL
```
    The directive value identifying an optional requirement resolution type. An optional resolution type indicates that the requirement is optional and the resource may be resolved without the requirement being resolved.
    
    See Also:
    
    REQUIREMENT_RESOLUTION_DIRECTIVE, Constant Field Values
  - REQUIREMENT_EFFECTIVE_DIRECTIVE
```
public static final String REQUIREMENT_EFFECTIVE_DIRECTIVE
```
    The requirement directive used to specify the effective time for the requirement. The default value is resolve.
    
    See Also:
    
    resolve, active, Constant Field Values
  - EFFECTIVE_RESOLVE
```
public static final String EFFECTIVE_RESOLVE
```
    The directive value identifying a capability or requirement that is effective at resolve time. Capabilities and requirements with an effective time of resolve are the only capabilities which are processed while resolving a resource.
    
    See Also:
    
    REQUIREMENT_EFFECTIVE_DIRECTIVE, CAPABILITY_EFFECTIVE_DIRECTIVE, Constant Field Values
  - EFFECTIVE_ACTIVE
```
public static final String EFFECTIVE_ACTIVE
```
    The directive value identifying a capability or requirement that is effective at active time. Capabilities and requirements with an effective time of active are ignored while resolving a resource.
    
    See Also:
    
    REQUIREMENT_EFFECTIVE_DIRECTIVE, CAPABILITY_EFFECTIVE_DIRECTIVE, Constant Field Values
  - REQUIREMENT_CARDINALITY_DIRECTIVE
```
public static final String REQUIREMENT_CARDINALITY_DIRECTIVE
```
    The requirement directive used to specify the cardinality for a requirement. The default value is single.
    
    See Also:
    
    multiple, single, Constant Field Values
  - CARDINALITY_MULTIPLE
```
public static final String CARDINALITY_MULTIPLE
```
    The directive value identifying a multiple cardinality type.
    
    See Also:
    
    REQUIREMENT_CARDINALITY_DIRECTIVE, Constant Field Values
  - CARDINALITY_SINGLE
```
public static final String CARDINALITY_SINGLE
```
    The directive value identifying a cardinality type of single.
    
    See Also:
    
    REQUIREMENT_CARDINALITY_DIRECTIVE, Constant Field Values
