I want to create an xml node that contains attributes as well as values.

Example:

```
<mynode attr1="hello">world</mynode>

```

I understand that

```
SELECT 'hello' as '@attr1' 

```

creates at least mynode, but how to attach "world" then?

I tried

```
SELECT 'world' as 'mynode/[@attr1=hello]' 

```

but it didn't work
