- Annotation Syntax, subannos

... subAnno1$[:   value  $]
           $|$[: { subannos } $]
           $|$[: [ arrelem ] $]
           $|$[.subAnno$[ ... $]$],
    subAnno2$[:   value  $]
           $|$[: { subannos } $]
           $|$[: [ arrelem ] $]
           $|$[.subAnno$[ ... $]$],
    ...

Effect

Comma-separated list of subannotations subAnno1, subAnno2, ... in the curly brackets of an annotation. The name of a subannotation can contain letters, numbers, and underscores only and must start with a letter. The same information can be specified after the name as specified after the main annotation:

A colon (:) followed by the following:

An annotation value value

Further subannotations subannos specified in curly brackets { ... }.

Elements of an annotation array arrelem in square brackets [ ... ]

The chaining of the subannotations subAnno1, subAnno2, ... with a further subannotation subAnno using a period (.).

Only those subannotations should be specified that are supported by the associated annotation definition.

Note

As well as by using a comma-separated list in curly brackets, individual subannotations can also be specified using individual structured annotation names.

Example

The following annotation definition is available.

The annotation can then, for example, be specified as follows:

@DemoSubAnnos: {subAnno1: true,
                subAnno2: { subAnno1: 1,
                            subAnno2: { subAnno1: 1,
                                        subAnno2: 2 } } }

This example has the same semantics as the example using structured names.
