How can I read the second `hcl:",key"?

```
test "aws_subnet" "privatenet" {
vpc_id = "xxxx"
cidr_block = "xxxx"
availability_zone = "xxxx"
map_public_ip_on_launch = false

tags {
"Name" = "xxxx"
"terraform" = "true"
}
}
```

Hi. I'm using this library for my work. but I can't read second title. "privatenet"

I'm testing this code.

```go
type Config struct {
Directories []DirectoryConfig `hcl:"test"`
}

type DirectoryConfig struct {
AwsSubnet string `hcl:",key"`
AwsSubnetName string // ????
VpcId string `hcl:"vpc_id"`
CidrBlock string `hcl:"cidr_block"`
AZ string `hcl:"availability_zone"`
MapPublicIpOnLaunch bool `hcl:"map_public_ip_on_launch"`
}
```

I want to read AwsSubnetName. But I don't know expression. I can't find it anywhere.

And other variables are not working except AwsSubnet.

Please help me.

The payload names no source file or test. Start by reproducing the Go decoding example against the supplied HCL input, then trace the library's handling of the hcl tags and labels. Done should mean the requested label and remaining attributes decode as intended, with a regression test documenting the behavior.
