authoring txtml : specifying states and blocks
At the first level following the root, a TXTML document contains one or more states and/or blocks. Each state or block has a name, which must be lowercase. This is specified as:
<txtml version="1.2">
<state name="state_1">
...
</state>
<block name="block_1">
...
</block>
</txtml>
<state name="state_1">
...
</state>
<block name="block_1">
...
</block>
</txtml>
