I think there is nothing for this built-in in diet, so you have 
to manually emit raw HTML:

```diet
- import std.xml : encode;
- auto start = appender!string;
- start ~= "<tag";
- foreach (pair; v)
     - start ~= " ";
     - start ~= pair[0].encode;
     - start ~= "=\"";
     - start ~= pair[1].encode;
     - start ~= '"';
- start ~= ">";
|!= start
// content here
|!= "</tag>"
```

Maybe some attribute splat operator would be nice for this.
