To hide attributes of tags, but keeping the tag's content inline,
another
 option could be added.
 It could change <tag attributes=...> to <tag id=#>.
 This could be used to avoid typos to be introduced in attributes if they
 are known to be untranslatable, and to reduce the amount of data that need
 to be translated. 
yes this sounds great. i don't really care if <a>s are changed into
<link>s 
or not; it actually makes more sense to just keep them as <a>s.
regarding whether adding id="#" adds clutter, in the case of our links, many 
of them look like:
"supports connection to hubs using the earlier <a 
href=\"http://en.wikipedia.org/wiki/Direct_Connect_network\" 
target=\"_blank\" class=\"external\">NeoModus Direct Connect
(NMDC)</a> 
protocol"
so yes, changing [href= target= class=] into a simple id="#" tag is much 
neater.
this could be useful in other places too, for example with <span> tags when 
these specify complicated CSS styles.
