xml schema design

[Andy B]

I have an xml schema that I am working on. I wanted to know if it was a
normal thing to do something like this:

1. Have a ZipCode simple type that has to be 5 characters long.
2. Have a StateCode simple type that has to be 2 characters long.
3. Have an Address complex type that has:
- Street (string)
- City (sgring)
- State (StateCode) [noted in item 2 above]
- ZipCode (ZipCode) [noted in item 1 above]
4. Have a Venue complex type that has the following:
- Name (string)
- Address (Address) [noted in item 3 above]
- PhoneNumber (string)
5. Have an element that can contain only 1 instance of the Venue complex
type.

Sounds fine to me, you might additionally restrict zip code to five
digits, enumerate the possible state codes.

digits, enumerate the possible state codes.

I forgot about the fact that I had ZipCode set to require 5 characters. I
want to make this a 5 digit number but cant find a length property for the
int or integer data type. How would I fix this? I have it set to ZipCode
(string) - length=5. You also said to make an enum for the state codes. How
exactly do I do this?

Straight from <URL:http://www.w3.org/TR/xmlschema-0/is this example:

<xsd:simpleType name="USState">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="AK"/>
<xsd:enumeration value="AL"/>
<xsd:enumeration value="AR"/>
<!-- and so on ... -->
</xsd:restriction>
</xsd:simpleType>

As for the zip code, one way is with a regular expression pattern:
<xsd:simpleType name="zipType">
<xsd:restriction base="xsd:positiveInteger">
<xsd:pattern value="\d{5}"/>
</xsd:restriction>
</xsl:simpleType>

Why would it be a good idea to do an enum for the state codes instead of
just letting somebody typing it in just a string field?

In terms of the W3C schema language I suggested an _enumeration_ below:

><xsd:simpleType name="USState">
<xsd:restriction base="xsd:string">
<xsd:enumeration value="AK"/>
<xsd:enumeration value="AL"/>
<xsd:enumeration value="AR"/>
<!-- and so on ... -->
</xsd:restriction>
</xsd:simpleType>

Or are you now talking about a .NET enumeration defined with C# or VB.NET?

You have the right thing. Does it do the same thing a c# enum would do?
either restrict the strings that can be used, or make useful names for
meaningless numbers (like a c# enum does)?

The simple type I posted is a restriction of xsd:string allowing only
the enumerated string values (e.g. "AK" or "AL") to be used.

Makes sense to me. I added all of the state codes to the schema.
