The String value of a StringExpression is obtained by concatenating, in order, the String values of either the operands or the subExpressions, depending on which is given. Source Unified Modeling Language 2.5.1
The substrings are given as either a list of LiteralString operands or as a list of StringExpression subExpressions (but it is not allowed to mix the two). Source Unified Modeling Language 2.5.1
A StringExpression is an Expression that specifies a String value that is derived by concatenating a list of substrings. Source Unified Modeling Language 2.5.1
A LiteralString is shown as a sequence of characters within double quotes. The String value is the sequence of characters, not including the quotes. The character set used is unspecified. Source Unified Modeling Language 2.5.1
A LiteralString specifies a constant value of the PrimitiveType String. Though a String is specified as a sequence of characters, String values are considered to be primitive in UML, so their internal structure is not specified as part of UML semantics. Source Unified Modeling Language 2.5.1
