ABENST_ADDRESSING_NODES_IN_COND - ST ADDRESSING NODES IN COND

- 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 in accordance with the preceding addressing rules, contains a letter or an underscore in its first place and only letters, digits, hyphens, or underscores in the remaining 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.
