But this *is* valid SGML.

<!doctype text [
<!element text - - (#pcdata)>
]>
<text>
foo < bar
   foo< bar
</text>

This was one of the complexities of SGML that was removed to make XML, 
in order to *make it easier to write parser/validators*. There were lots 
more, and I'm sure no-one involved at that stage would claim that 
everything was got right. Don't forget that XML was designed for *text 
documents*; any other use was either an afterthought or simply Not Yet 
Invented.
