 * PascalCase
 * UpperCamelCase
 * resourceAPIKey
+* enableSSL
 
 **Bad Examples**: The following violate these guidelines but would not be caught by automation: 
 * alllowercase - If there are multiple words, please capitalize starting with the second word
 * miXeDcApItAlIzAtIoN - Please capitalize the first letter of each word (and not seemingly random letters)
+* resourceAPIkey - Automation would incorrectly recognize "Ikey" as a word and not flag the property name
