81 \brief The DynamicParameter (previously \l MapParameter ) type represents a parameter for a Map element,
82 or other elements used in a Map (such as map items, etc.).
83 This type provides a mean to specify plugin-dependent optional dynamic parameters that allow a plugin to
84 extend the runtime API of the module.
85
86
87 DynamicParameters by default contain only the \l type property, and
88 are highly plugin-dependent.
89 For this reason, additional properties have to be defined inside a
90 DynamicParameter at declaration time, using the QML syntax "property var foo".
91
92 What properties have to be put inside a particular DynamicParameter type for
93 a particular plugin can be found in the documentation of the plugin.
94 \note DynamicParameters are \b optional.
95 By not specifying any of them, the Map, or other container elements, will have the default behavior.
