Variables may appear anywhere within a string value, and multiple variables can be used within the same value. Variables take the form:
variable := '${' variableNames [ ':' defaultValue ] '}' variableNames := variableName [ ',' variableNames ] variableName := /* any characters except ',' and ':' and '}' defaultValue := /* any characters exceptNote that variableName is the name used to look up the
Properties
property.
Notice that the syntax supports multiple variables. The logic will process the variables from let to right,
until an existing System property is found. And at that point, it will stop and will not attempt to find values for the
other variables.

Variables may appear anywhere within a string value, and multiple variables can be used within the same value. Variables take the form:
variable := '${' variableNames [ ':' defaultValue ] '}' variableNames := variableName [ ',' variableNames ] variableName := /* any characters except ',' and ':' and '}' defaultValue := /* any characters exceptNote that variableName is the name used to look up a System property via

.
Notice that the syntax supports multiple variables. The logic will process the variables from let to right,
until an existing System property is found. And at that point, it will stop and will not attempt to find values for the
other variables.
Because only string values can contain variables, the resulting values are left as strings. This may not be valid according
to the document's JSON Schema, so see SchemaLibrary.convertValues(Document, String)
to convert the string values
after variable substitution into the expected non-string types.
