Define value content of an attribute in construction.
This expression is part of an AttributeValue. It defines the
content of an attribute value when using a constructor expression. As literals
it allows any defined character, a character reference such as
א, a predefined entity references such as
", and two escape sequences for the left and right brace.
Since the braces are used to delimit enclosed expressions, an escape sequence
is necessary to use the braces as literals. For that purpose, two adjacent
braces are interpreted as a single literal brace.
Furthermore, content can be determined by an enclosed expression that contains an expression which is evaluated and the result placed as element content.
See AttributeValue for examples.
