Ate Douma resolved SCXML-99.
----------------------------

    Resolution: Fixed

> support read-only system variables
> ----------------------------------
> 
> Key: SCXML-99
> URL: https://issues.apache.org/jira/browse/SCXML-99
> Project: Commons SCXML
> Issue Type: Bug
> Affects Versions: 0.9
> Reporter: Ingmar Kliche
> Assignee: Ate Douma
> Fix For: 2.0
> 
> 
> The SCXML WD [1] describes a set of system variables which are read-only for the \
> application. See section 5.5 [2]: "The Data Module maintains a protected portion of \
> the data model containing information that may be useful to applications...." It \
> may necessary to abstract out the notion of a partitioned root context, just like \
> we have a notion of ordinary context. The implementation should take into account, \
> that some expression languages support read-only behaviors natively (such as \
> ECMAScript through scope chains), whereas other expression languages (or there \
> implementations resp.) don't.  [1] http://www.w3.org/TR/2008/WD-scxml-20080516/
