Shebangml/Syntax.pod - about the #!ml syntax

Shebangml is a human-writable syntax for xml. Unlike YAML, HAML, and various other shorthands, it directly expresses the xml structure (nodes have attributes and/or content),
node{The content goes here}
node[with="just attributes"]
node[with=attribute]{and content!}
The syntax is just that, and not much more.

As you may have noticed, attributes do not need to be quoted if they have no spaces or special characters.
'\n;' => '<br/>'
These commonly used attributes may be shortened as long as the value is a simple string and all shortcuts occur before any full attributes.
'=foo' => 'id="foo"' ':foo' => 'name="foo"' '@foo' => 'class="foo"'

The content of an element surrounded with {{{ and }}} will be passed through without parsing. This can be done on a single line or as start/end tokens for a multiline block.
whatever{{{ no parsing in{here} at all }}}
whatever{{{
Or some multiline thing, but you have to stop this section at the
beginning of the line.
}}}
