Re: [editing] Legal caret positions – invisible text nodes (#75)

> PS. CKEditor actually normalizes all white spaces when loading data, so such situations with white-spaces are unlikely to happen in it. Perhaps we could refer to or define similar normalization in the spec to simplify the rules.

I think this is stuff the editor has to do. There can be many preferences for how to store spaces in texts and there is no good reason for us to mess with it at this stage. The caret should simply be placeable (programatically) anywhere in text nodes. Rule 1 states that already. So those text nodes do not fall under the definition of invisible.

If you don't feel that the commit addresses your concerns, please reopen this issue.
