    </sentence>
</aligned-text>
`;


const App = () => (
  <Alignment alignment={xml}>
    <Sentence n="1">
      <Segment lnum="L1" />
      <Segment lnum="L2" />
      <Comments />
      <Collapse title="XML">
        <Xml />

    </Sentence>
  </Alignment>
);

export default  App;

#### Alignment

The `<Alignment>` component accepts an XML document of an alignment as an `alignment` prop.
The other components should be children (or grandchildren, etc.) of the `<Alignment>` component.

#### Sentence

The `<Sentence>` component accepts a string `n` which represents the `n` of the
sentence to display.

#### Segment

The `<Segment>` component shows the text of one of the languages. It takes an `lnum` prop for
the `lnum` of the language to display.

#### Comments

The `<Comments>` component displays comments associated with any of the active words. If there
are no comments, it does not render.

#### Xml

The `<Xml>` component displays the XML of the sentence.

#### Collapse

The `<Collapse>` component is provided for convenience.
It is a button that displays or hides its children whenever it is clicked.
