6. Safe mode

There are three ways to enable safe mode:

Command line (long): --safe-mode[=boolean]
Command line (short): -S
Java system property: com.xmlcalabash.safe-mode=boolean
XML configuration: <cc:safe-mode>boolean</cc:safe-mode>
Ant task: <calabash safeMode="Ant boolean"/>

If safe-mode is enabled, only XProc standard steps can be instantiated and any attempt to access the local filesystem will result in a dynamic error.
