> There are a few issues here. First, the following YAML is totally broken;
> {code}
>               dependencies:
>                 - ssh.address > { get_attribute: virtual_ip.floating_ip }
> {code}
> The problem is that in YAML, due to the location of the ":", this gets parsed as a dict where the key is {code}ssh.address > { get_attribute{code} and the value is {code}virtual_ip.floating_ip }{code} which is not what we want at all.
> The solution is to encase the whole value in quotes to enforce parsing as a string:
> {code}
>               dependencies:
>                 - "ssh.address > { get_attribute: virtual_ip.floating_ip }"
> {code}
> Note that the one attractive solution is to to change this ">" format to a real dict. So:
> {code}
>               dependencies:
>                 - { ssh.address: { get_attribute: virtual_ip.floating_ip } }
> {code}
> But this will break other TOSCA parsers that expect a string here, so no go. :(
