Some examples from the URI manipulation section are not correct

[raducotescu]

The following examples are incorrect:

1. example.com is not a valid domain in this context:

   ${'example.com/path/page.html' @ scheme='http'}
   <!-- outputs: http://example.com/path/page.html -->

2. selectors should not be merged, but rather appended

   
   ${'path/page.woo.foo.html' @ addSelectors='foo.bar'}
   <!-- outputs: path/page.woo.foo.bar.html -->

${'path/page.woo.foo.html' @ addSelectors=['foo', 'bar']}
