case sensitive

基本解釋

This check is also case sensitive.
此檢查也是區(qū)分大小寫的。
Whilst the attribute names are not case sensitive, the values may be (unless compared with ~=).
屬性名不是大小寫敏感的，值可能是（如果不用~=作比的話）。
You can escape these rules by placing the name in double quotation marks, which allows names to be case sensitive and to include additional characters (including spaces).
通過把名稱放在雙引號中，可以避開這些槼則，使用雙引號允許名稱區(qū)分大小寫以及包含附加字符（包括空格）。

Add in letters and you have 26 (case-insensitive) or 52 (case-sensitive) more options.
