Re: [apps-discuss] New I-D: text/markdown Media Type - draft-seantek-text-markdown-media-type-00

I predict that when you look at the variants they will divide up into one
set that is based on some sort of FSR or Lexer and the other being based on
pattern matching.

While these approaches are close in theory, there are very important
differences in practice. Pattern matching tends to be done without regard
for quoting or escape mechanisms and make assumptions about the well
formedness of the text.

There is a school of HTTP header 'parsing' that just scans for the text
sequences of interest. So if someone puts in a header like the following,
chaos ensues:

X-Ignore: Content-Length: 103
Content-Length: 2048

Of course scanning for "\r\nContent-Length:" would not fall into this trap.
But folk tend not to think that way.
