ST - Data Nodes in Conditions
For addressing data nodes in logical expressions, a special rule applies. Data nodes as dnode operands of preconditions, assertions, or conditions can be specified as follows:
- If the name node # specified according to the preceding addressing rules # has a letter or underscore as its first character and only letters, numbers, hyphens, or underscores in all other positions, it can be specified directly.
- The special names $ref and $alias can also be specified directly.
- All other names must be specified in the form ref('node'). This particularly applies to the specification of a data root using .root.
