The accepted answer on that stackoverflow page you linked to is actually not
correct, or let's say not precise. XML allows the ' and " as node content, they
only need to be escaped when they appear in attribute values. As the XML
property list format does not use attributes, a situation where a ' or "
needs to be escaped does not occur. The characters that must be escaped in node
content are & and <. This is taken care of by the library as it wraps any
strings containing these characters into CDATA sections, where the > character
is also escaped.
For definite information on that topic see section 2.4 of the latest XML
specification at http://www.w3.org/TR/xml/#syntax.
