Rendering precedence is a different subject to tagging. You know
what happens to suggestions of tagging in a certain way for the
purposes of influencing the appearance of a map...<br>

<br>
You're misunderstanding the purpose of tagging which is to allow
renderers to differentiate entities & display them accurately
& differently from each other. <br>
<br>
*All* tagging is for the renderer, it's incorrect tagging that's
frowned upon (natural=sand for golf bunkers is the popular example).

A search on the wiki for pages with the word primary only returns
hits in connection with highway and schools. Can you help me out
and give a link to the page you are referring to?<br>
</blockquote>
<br>
Many pages list tags 'to be used in conjunction with...'<br>
<br>
A good test is if you remove a tag & it fails to render then
it's probably a primary tag. Sub tags allow you to add extra
adjective attributes.<br>
<br>
Example (made up one):<br>
barrier=gate (primary)<br>
<br>
Sub tags:<br>
access=yes<br>
type=5 bar<br>
material=wood<br>
colour=blue <br>
<br>
Delete the sub tags & they'll probably still render. delete the
primary & it won't.<br>
<br>
