Multiple styles per element with cascade like CSS
So many documents get output into electronic formats now. The limitation of only one style per element (paragraph, character, object) makes it difficult to map what is happening in InDesign to good HTML and CSS.
If InDesign allowed multiple styles to be applied to an element, with cascade rules like CSS, then electronic output would be easier and the quality of generated markup could be improved. In addition, being able to apply simple style changes to override more comprehensive styles would simplify documents and reduce the number of styles needed to make little variations of design possible..

It would be awesome if indesign adopted CSS as the ability to manage typographic styles across multiple documents :)
