Mixing list types does not work correctly. Example:

# order
# order
#* point below
# order
#: definition term
# order

A minimal example is:

    [[foo=bar]]

Discovered with the following markup, with a backend which expands "ex:".

    {{ex:113} {{ex:122}} {{ex:119}}

Detail: This causes it to look for a template called "ex:113} {{ex:122", which is bogus, so the custom getTemplateMarkup("ex:113} {{ex:122") returns "[[ex:113} {{ex:122]]". From here, the template on the right is expanded and returns HTML markup. The markup contains '=', so is treated as variable-argument (like [[image:foo|width=2em]]), and the back-end attempts to render this:

    [[ex:113}  <whatever class="...">...</whatever>]]

Triggering the PHP warning:

    Notice: Undefined offset: 0 in WikitextParser.php on line 905

This element is not currently supported.

Example from http://www.mediawiki.org/wiki/Help:Tables

    {|
    |+Food complements
    |-
    |Orange
    |Apple
    |-
    |Bread
    |Pie
    |-
    |Butter
    |Ice cream 
    |}

This will not render correctly with this parser, due to the table caption.

Example of this causing problems:

    Beeble:
    * Foo
    ** Bar
    <!-- Baz -->
    ** Quux

The comment is rendered in its own paragraph (like 'Beeble' is), and this produces two list structures, rather than one.

An unclosed external link causes:

Fatal error: Call to undefined method (backend class)::processArgs() in /home/mike/workspace/samoan/vendor/wikitext/WikitextParser.php on line 414

Documented here

MediaWiki does not put line breaks between items written on separate lines. This will be replaced with a space instead.

Because the parser checks for close-tags before it checks for new open-tags, this sequence will render as if the italics were closed originally:

normal text ''italic text '''bold inner text''' still italic '' back to normal

Tags need to be evaluated in descending order of length, regardless of whether they are open or close tags.

As a developer who wants to use this package
I want to include it as a Composer dependency
So that it works like all the other libraries out there.
