To be fair, sometimes design decisions which make an editing/validating product generally
pallatable in use can be (or be perceived as) bugs from the user's POV at the end of the day.  
The very thing that makes an editor rich makes a validator poor, as the song says. When 
editing, at one moment a user is focused on some issues (say, elements) but not others 
(say, special characters), then later the user is focused on another set of issues.  

One of the major distinguishing differences between editors is how the provide progressive 
or piecemeal or partial or feasible validation.  But the tradeoff is that the more options a vendor
provide a user to filter out things they are not interested in at one time, the more they are required
to know. People want a big single button marked "Validate", but they also don't want to get
swamped with too much information, and they also want to trust their tools.

(One nice approach for having cake and eating it is to provide a sortable list of all found
errors, so that the user can just look at the ones they are interested in, grouped.)
