Oh, there are many. This phenomenon is not unique to the XML family of 
languages. I would go so far as to say it is the norm.

Example 1: Regular expressions in the Python programming language

s = r"\s\tWord"
prog = re.compile(s)

 From the Python language point of view, s has a character string value. 
It turns out that this value is an expression in a different language, 
the Python regular expression language. (This particular regular 
expression is very simple. It has no repetition operators like '*' or 
'+'.) Read more about Python and regular expressions at my answer 
<https://stackoverflow.com/a/13836171/1099571> to the Stack Overflow 
question, /What exactly is a "raw string regex" and how can you use it?/

Example 2: Human-readable text in just about any language

s = "This is human-readable text"

This expression is a valid in many different programming languages. s 
has a character string value. It turns out that this value is an 
expression in a different language, the English language.
