Counting the no of elements doesn't seem to be a bad idea unless you have some exceptions.
And where does this <Desc> tag exactly appear?

PPI::Token::End(3pm)					User Contributed Perl Documentation				      PPI::Token::End(3pm)

NAME
PPI::Token::End - Completely useless content after the __END__ tag INHERITANCE
PPI::Token::End isa PPI::Token isa PPI::Element DESCRIPTION
If you've read PPI::Token::Whitespace, you should understand by now the concept of documents "floating in a sea of PPI::Token::Whitespace". Well it doesn't after the __END__ tag. Once you __END__, it's all over. Anything after that tag isn't even fit to be called whitespace. It just simply doesn't exist as far as perl (the interpreter) is concerned. That's not to say there isn't useful content. Most often people use the __END__ tag to hide POD content, so that perl never has to see it, and presumably providing some small speed up. That's fine. PPI likes POD. Any POD after the __END__ tag is parsed into valid PPI::Token::Pod tags as normal. This class, on the other hand, is for "what's after __END__ when it isn't POD". Basically, the completely worthless bits of the file :) METHODS
This class has no method beyond what is provided by its PPI::Token and PPI::Element parent classes. SUPPORT
