Help meunderstand how this translates into

[Venkat Venkataramanan]

I picked up this fragment from a DTD:


<xs:complexType name="oversight_info_struct">
<xs:sequence>
<xs:element name="authority" type="xs:string" minOccurs="0" maxOccurs="unbounded"/>
<xs:element name="has_dmc" type="xs:string" minOccurs="0"/>
</xs:sequence>
</xs:complexType>

Does this mean:

1. The XML can have Zero-to-many instances of the element, authority"
2. Each authority element may or may not have an element, "has_dmc"

The oversight_info_struct element type can have 0 or more child elements named "authority". Here's an example (assuming "oversight" element is of type oversight_info_struct):
<oversight> <authority>foo</authority> <authority>bar</authority> </oversight>

No. Notice that the "oversight_info_struct" is being defined there and not the "authority" element. So it means that the oversight_info_struct type can have 0 or any number of child elements named "has_dmc".
