XML false vs (string) false

Question

How can I represent, true/false as the Boolean and "true"/"false" the strings in XML?

Eg.

<problem>false</problem>
<problem>problem_name</problem>

Or is there a better way to do this?

Answer 1

According to the spec, you can use the literal values true, false, 1, 0 but you should use true or false only.

"3.2.2 boolean

[Definition:] boolean has the ·value space· required to support the mathematical concept of binary-valued logic: {true, false}. 3.2.2.1 Lexical representation

An instance of a datatype that is defined as ·boolean· can have the following legal literals {true, false, 1, 0}. 3.2.2.2 Canonical representation

The canonical representation for boolean is the set of literals {true, false}."

Answer 2

It is a common unwritten rule that says in xml as a boolean value we should use: 'true' and 'false'
