Construct octet values for attributes

[work vlpl]

How I can construct octet value for VSA if some octet in it has to be `0x00`?

For example I can set value for VSA using expression like this

```
VSA-Name := '\001somevalue'
```

or

```
VSA-Name := 0x01736f6d6576616c7565
```

But when I tried to use this expression

```
VSA-Name := '\001\000somevalue'
```

All data after \000 are truncated
