RE: Empty element tags

What if I am not writing HTML.   It seems odd that an uXML parser would complain if I wrote <br></br>
but not <foo></foo>

Wouldn't it be simpler to simply let users hang themselves as if they were writing HTML ?

Both <br> and <br/> work to force a line break; indeed, loose slashes are
always ignored in HTML5 start tags.  Unfortunately, </br> *also* forces
a line break, so <br></br> will give you two line breaks.  This is why
my editor's draft has a special rule requiring any element named "br",
when empty, to be expressed with an empty-tag.  (No semantics are given
or required).

Fortunately, no other HTML element has this property.  If you write <meta
blah-blah-blah></meta>, the close-tag is just ignored.

ok, thank you for explanations.
