Hi all,

I am looking for a effective way to express lists of different string
compounds - i.e. list of names defined by a number of different
enumeration types. To be precise, I would like to express a list of
string names : String name list = [Name1 | Name2 | Name3 ...]+

The result should be ONE string which can be validated.

Imaginary example:
 Using the two names:

 <xsd:simpleType name="Name1" base="xsd:string">
  <xsd:enumeration value="RED"/>
  <xsd:enumeration value="BLUE"/>
  <xsd:enumeration value="GREEN"/>

<xsd:simpleType name="Name2" base="xsd:string">
  <xsd:enumeration value="BIG"/>
  <xsd:enumeration value="SMALL"/>

 I would like to construct a single string which is a list of intermixed
names Name1 and Name (syntax made up):

<xsd:simpleType name="NameList" base="Name1 | Name2"

To allow a nameList element of type NameList to contain:

<nameList>BIG BLUE</nameList>
<nameList>SMALL GREEN RED</nameList>

etc.... but NOT

<nameList>BGI BUE</nameList>

I would find such a thing quite useful when dealing with strings and
arrays which are compounds.
