ins nested within elements, elements nested within ins

Classified as: flow content, phrasing content, palpable content

Parents, ins

Children, ins

transparent content model:
ins content model = transparent → ins element accepts the elements its parent accepts
(the elements, possible parents of the ins element, are listed above)
e.g.
1: p element, parent of the ins element
<p> <ins>... <⁄ins><⁄p>

2: p element accepts the a element as child
<p> <a> ... <a⁄><⁄p>

Conclusion: if the p element accepts the a element as child, then the ins element will accept it too
<p> <ins> <a> ... <a⁄> <⁄ins><⁄p>

Examples: ins parents, ins children
