I wrote this sentence
The node features, which are used to create a condition, are selected from a list showing the available features
or
The node features, which are used to create a condition, are selected from a list, which shows the available features
Why?
I myself somehow prefer the second sentence
By the way now I think if I start with the available node features, ..., I don't need a relative clause. However, I still like to know the possible difference here.
They both are correct, but slightly unusual. I suppose nobody will actually be physically looking at that list, so it is slightly odd to say that the list shows those features. It would be much easier and probably more idiomatic to say that those features are selected from a list of the available features.
The node features, which are used to create a condition, are selected from a list of available features.
This is also a lot shorter, leaving you with a more concise sentence.
In this case, there is not really any difference between using the definite (the) and indefinite (zero article) article. However, using the zero article might, but not necessarily, imply that the list does not contain all of the available features that exist, while the definite articles implies that all of the features are included in the list.
