Added some color to three use cases ~~~~
| TLD Validation in programming languages
| Numerous programming languages use the PSL to validate form entries or logic determining validity of TLDs where PSL is used to validate the rightmost apex of TLD.
| In this form value someone just submitted for the URL of their API, was the TLD valid?| com, co.uk, appspot.com
|
|-
| Anti-Spam
| The rightmost apex of TLDs is reviewed for validity on return/sender addresses as a basic check, using match in PSL as initial pass/fail to reduce processing time.
| Should I quickly drop this email FROM: perp@scam.you if .you isn't in the list of TLDs?| con, co.uk, appspot.com
|
|-
| Whois or other TLD related client software
| Use of PSL to track delta/changes/additions to list of possible TLD extensions for purposes of determining whois servers for distributed clients.
| What changed in the last version of the PSL, so I know what needs to get attention specifically?| com, co.uk| appspot.com
