Fundamental Question of XML

[Hoyin Chan]

I am not very sure about the *, +, | and () used to identify the quatity of the element.
Like:
If the DTD is: <!ELEMENT tag1 (tag2 | tag3*)+>
What does this mean??
Is it correct to say
  <tag1>
    <tag2>
    </tag2>
    <tag2>
    </tag2>
  </tag1>
?
And can I use both tag2 and tag3 inside tag1?
