Good point about the difference between compiling and merely parsing. 
Still in my limited experience (one university, but a relatively 
prestigious one) graduate students did not write a C compiler as part of 
their compiler course, much less undergraduates. They wrote a compiler 
for  a stripped down language that looked like C but wasn't because all 
the difficult bits had been pulled out. I don't want to see a lot of de 
facto XML subsets in every other program. Making a parser simple enough 
that a lot of people *think* they can write one quickly is asking for 

Note I don't doubt that writing an XML parser is well within the 
capabilities of many hundreds of thousands of programmers. I just doubt 
that a programmer who is not fully focused on XML will write a correct 
parser, even if the language is simplified. Furthermore, I do not think 
it is in their interests to do so, compared to whatever other jobs they 
have to accomplish. It's better for everyone if they just use the 
available, high quality off-the-shelf parsers.
