-## HTML5's 'id' attribute requirements are:
-## - Must be at least one character in length.
-## - Must not contain ASCII whitespace.
-## - Must be unique within the document.
-## - No other requirements. (HTML4 had stricter requirements.)
-
-## Python-Markdown's default ID formula (as of v3.1.1) is:
-## 1. normalize unicode to NFKD form (so it can strip accent marks)
-## 2. remove all non-ASCII characters (this is the problem for us)
-## 3. remove leading/trailing whitespace
-## 4. convert to lowercase
-## 5. remove everything except space, hyphen, alphanumerics, and underscores
-## 6. replace each block of consecutive whitespace/hyphens with a single hyphen
-## 7. add _1, _2 etc. suffixes to non-unique IDs
-## Later, the dev portal uses a filter to replace underscores with dashes.
-
-## The new formula is similar, but has some important differences:
-## 1. No Unicode normalization. We'd rather leave things as-is.
-## 2. Leave the string as unicode throughout.
-## 5. Keep hyphens, unicode "space" and unicode "word" characters (includes
-##    underscores). Replace everything else with spaces, then strip trailing
-##    spaces.
-## 7. Add -1, -2 suffixes to non-unique IDs.
-## The end result is that this standard closely matches GitHub-flavored
-##     Markdown in almost all cases. (The exceptions are cases where GFM makes
-##     invalid empty IDs, for example with emoji headers...)
