Hi all,

On Page 557, Q17, I don't understand why A is correct. This is because the question mentioned that "Both tags are declared to be non-empty and non-tag dependent in the TLD". But as A :

<my:simpleTag>
<my:complexTag />
</my:simpleTag>

It seems that complextTag is empty body. So why A is the correct answer?

Thanks
David

Even if complextag is defined "not empty" , Keeping it empty will not cause any error and si valid. The other way around will cause error though.
