case sensitive

基本解釋

This check is also case sensitive.
此檢查也是區(qū)分大小寫(xiě)的。
Whilst the attribute names are not case sensitive, the values may be (unless compared with ~=).
屬性名不是大小寫(xiě)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(guò)把名稱放在雙引號(hào)中，可以避開(kāi) 這些槼則，使用雙引號(hào)允許名稱區(qū)分大小寫(xiě)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.
