<p>A metadata string is a string surrounded by double quotes. It can contain
- any character by escaping non-printable characters with "\xx" where "xx" is
- the two digit hex code. For example: "<tt>!"test\00"</tt>".</p>

<p>Metadata nodes are represented with notation similar to structure constants
(a comma separated list of elements, surrounded by braces and preceded by an
- exclamation point). For example: "<tt>!{ metadata !"test\00", i32
- 10}</tt>". Metadata nodes can have any values as their operand.</p>
