Use Cases & Exploratory Approaches for Ruby Markup looks at a number of use cases involving simple and complex ruby, and considers which are supported by the current markup models in the HTML5 and XHTML Ruby Annotation specifications. Where a use case is not supported by the HTML5 model, it provides suggestions about how the markup model could be adapted to better support those use cases. In each case, pros and cons of the approach are listed, but the document does not attempt to impose a particular solution.
The hope is that implementers and standards developers will take the information and suggestions in this document as a starting point for developing a markup model for ruby in HTML5 that fully supports the use cases.
