First off that is NOT a typo; there are no quotation marks around the XML that you declare.
首先注意这并不是一个输入错误;在声明的XML周围没有引号。
If the single quotation mark is the outermost quote, no variables are expanded.
如果最外边的引号是单引号,那么不展开变量。
So if I take away the quotation marks, all I have is the word with no indication that it's a concept.
所以如果我拿掉引号,剩下的就只是这个词而不指示一个概念了。
