Issues and questions when validating agains epubcheck4

Good morning,

Questions first:

Does the epub3 stylesheets honor the css.decoration parameter? 

if css.decoration is not honored is there a way to strip all inline styles that doesn’t involve global search and replace?

Is there a way to add titles to links?

Reason why I ask is that  when working with epubcheck4 it complains a lot about inline styles and accessibility (and inline styles make custom CSS harder). 

When I look at the generated HTML I see the following examples of inline styles

Table border for block quotes and callout lists has a border attribute

TD elements inside the tables  have an inline  width style attribute

TD elements for blockquote attribution have an align attribute

It expects heading rows to have th elements instead of td, even in tables that are being used for layout

epubcheck also complains about links that have no text: The callout links on callout lists are images only.  I’m not 100% sure how that works as far as screen readers are concerned.
