Re: [Specifications] Should blank nodes be ignored in member assertion by default? (#248)

I think your approach is an overkill - I believe whole `memberAssertion` block should look like this:
```turtle
<book-languages> 
  hydra:memberAssertion
    [hydra:property dcterms:language],
    [
      hydra:property rdf:type;
      hydra:object bibo:Book
    ]
.
```

It should be interpreted as _each resource at book-languages has a predicate of dcterms:language and another predicate of rdf:type of which value is bibo:Book_. As for having a blank node used as a value of `hydra:object` in my example - indeed it might be troublesome for the client to figure it out what's inside. We could add a statetement in the spec that recommends using non-blank resources here.
