  - #### description

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Free-form textual description of the object. It is supposed to describe the object or a construct that it is attached to.

    This information may be presented to midPoint users, even to ordinary end users. For example role description may be presented to users when they are selecting roles to request. Therefore the description should be written in a language that the users can understand.

    Description is assumed to be a plan, non-formatted text. Amount of white space is considered insignificant. E.g. leading and trailing white space may be skipped, multiple spaces can be collapsed to one and so on.

  - #### documentation

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Technical documentation for a particular object or construct.

    The purpose of this element is to document system configuration and behavior. The documentation will not be presented to end users. In fact, it will probably not be presented at all in midPoint user interface. This documentation element is supposed to be a part of the technical documentation of midPoint deployment. The tools than generate deployment configuration will look for these elements and combine them to compiled documentation document.

    AsciiDoc formatting is assumed for this element. Any leading or trailing whitespace is skipped. Indentation equivalent to he indentation of the first non-blank line of text is also skipped.

  - #### trace

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Explicitly trace the execution of this expression. The execution will be logged on INFO level if this property is set to true to make sure that it will be visible in the logs.

  - #### relativityMode

    Flags: RAM,runtime,AVals:2

    Multiplicity: [0,1]

    Relativity mode of an expression, whether expression is processed in relative or absolute more. In relative mode the inputs are provided to the expression one-by-one. In absolute mode all inputs are provided to the expression at the same time.

  - #### includeNullInputs

    Flags: RAM,runtime

    Multiplicity: [0,1]

    If set to true (which is the default) the script will be evaluated with null value as argument when the input is changed from or to an empty value. This generally works well for most cases. It may be set to false as an optimization. Note: default setting for this property may be overridden in specific expression evaluators.

  - #### condition

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Condition driving whether this expression is evaluated at all (for given inputs).
