Hello

I'm preparing a new paper on XML Schema and two issues are unclear to me. 
Id be grateful for any clarifications.

Specifically, when an element contains a sequence of elements, I use 
xsd:complexType to define it. My question is do I have to insert a 
xsd:sequence element in there or can I just list the element?

The primer uses sequence in every example as in:

<xsd:complexType name="Address">
    <xsd:sequence>
       <xsd:element name="street" type="xsd:string"/>
       <xsd:element name="city" type="xsd:string"/>
    </xsd:sequence>
</xsd:complexType>

but I have found examples without it, as in:

<xsd:complexType name="Address">
    <xsd:element name="street" type="xsd:string"/>
    <xsd:element name="city" type="xsd:string"/>
</xsd:complexType>

I could not find in the standard (part 1) a clear answer on which one is right.

The second issue is I'm not sure I understand the practical differences 
between xsd:group and xsd:sequence.

Thanks for any help, pointer, etc.
