        Markaya is a YAML-based text-to-html conversion convention,
        Similar to Textile, but using YAML as its syntax. Any Markaya
        document is also a valid YAML document.
    
    - p: >
        The major goal of Markaya is to provide a full one-to-one mapping
        convention between YAML and XHTML. There are lot of ways to
        conver between a YAML document, and an XHTML document. Markaya
        syntax is also optimized for human, instead of machines, to
        read or to write Markaya documents. Balance between the fact
        that XHTML are too verbose to write, and syntax errors happens
        very easily. For example, here's a simple Markaya document:
    
    - pre: |
        html:
          - head:
            - title: Markaya Example
          - body:
            - h1: Hello World
            - p: This is an example
  
    - h2: Markaya Documents

    - p:
        A Markaya docuemnt contain one root node keyed "html", with
        a sequence value that should contain only two key-value
        pairs with keyname "head" and "body", in that sequence.

    - p: >
        All nodes except for the root node, should be an sequence of mapping or strings.
        Sequences can preserve ordering, and mapping are used to map YAML synatx to HTML
        tags. Most of the nodes in a sequence should contain only one mapping. Like this:

    - pre: |
        - p: Nihao

    - p:
        But it's OK to have a sequence of strings. And that should
        be the same as concatinating those strings altogether in
        that order.

    - p: >
        HTML documents always come with nested tags mixed within
        text conent. In Markaya, a sequence of mix of strings and
        mappings are used for this purpose:

    - pre: |
        - p: 
          - Hello, 
          - a href="http://who.int": World
          - . It's a beautiful day.

    - p:
        All string literals in a Markaya document are shown literaly
        when compiled to HTML. Which implies that no inline HTML
        is allowed.

    - h2: Mapping XHTML Tags
  
    - p: >
        Simple XHTML Tags are mapped to a key-value pair in a sequence. For example:
    
    - pre: |
        <p>Niaho</p>
    
    - p:
        Is mapped to  
    
    - pre: |
        - p: Nihao

    - p: >
        Tags with attrubtes are also mapped to a key-value pair in a sequence, but with
        attributes in-lined as a part of key. For example:

    - pre: |
        - p class=description: Nihao

    - p: >
        If you need spaces inside an attribute value, you can quote the value
        with double quote:

    - pre: |
        - p class="salut description": Nihao

    - p: >
        Inline tags are simply a tag within text sequences. For example, to do this in HTML:

    - pre: |
        <p>Hello,<a href="http://who.int">World</a></p>

    - p: >
        Just say this:

    - pre: |
        - p: 
          - Hello, 
          - a href="http://who.int": World
