Ruby Markup Content Model: some explicit and implicit base units, one implicit rtc as the first level annotation, an explicit rtc with some explicit and implicit annotation units as the second level, and a spanning annotation as the third level.

The example below consists of 3 base characters, each annotated twice, and then all jointly annotated once more. “あ” is annotated by “1” and “a”. “い” is annotated by “2” and “b”. “う” is annotated by “3” and “c”. The whole is annotated with “altogether”. For ease of comparison, it is preceded by some context text: “例文は”. This test passes if:

• each base character is presented inline with and similarly to the context text, as if they are all part of the same sentence, and
• each annotation is presented as an annotation, and
• the correct annotation is presented clearly as being associated with the correct base, and
• the joint annotation is associated with the whole base, not just a part.

Note: The colors are not part of the test, they are merely provided as help to the person running the test, to make it easier to recognize the various parts of the text.

Note: This is not a layout or rendering test. The precise appearance is not specified, and implementations may therefore validly vary.
