Detailed Description

An oval variable resolves an oval_value stream which specifies constraints for oval_objects and oval_states.

if oval_variable_type == OVAL_VARIABLE_EXTERNAL
- The value stream is determined by oval_definition_model_bind_variable_model
if oval_variable_type == OVAL_VARIABLE_CONSTANT
- The value stream is determined by a set of specified constants (see oval_variable_add_value)
if oval_variable_type == OVAL_VARIABLE_LOCAL
- The value stream is specified by either a single component or a complex function, meaning that a value can be as simple as a literal string or as complex as multiple registry keys concatenated together. Note that if an individual component is used and it returns multiple values, then there will be multiple values associated with the Oval_local. For example, if an object is specified as the local source and it references a file object that identifies a set of 5 files, then the local variable would represent these 5 values.
