xml schema: rule between atribute value in one element

[ocelka]

I need know how define xml schema for this xml fragment:

<set name="person-id" value="secure-card"/>
<set name="person-id" value="thumb-print"/>

<set name="length-unit" value="inch"/>
<set name="length-unit" value="cm"/>

so if name="person-id", then value can contain only one of value
"secure-card","thumb-print".
if name="length-unit", then value can contain only one of value
"inch","cm"

You can't define that in XML Schema. What you can do is define the
following:

<personID value="secure-card"/>
<personID value="thumb-print"/>
<lengthUnit value="inch"/>
<lengthUnit value="cm"/>

using the following schema:

<xs:element name="personID">

<xs:complexType>

<xs:attribute name="value" type="personAtt"/>

</xs:complexType>

</xs:element>

<xs:element name="lengthUnit">

<xs:complexType>

<xs:attribute name="value" type="lengthAtt"/>

</xs:complexType>

</xs:element>

<xs:simpleType name="personAtt">

<xs:restriction base="xs:string">

<xs:enumeration value="secure-card"/>

<xs:enumeration value="thumb-print"/>

</xs:restriction>

</xs:simpleType>

<xs:simpleType name="lengthAtt">

<xs:restriction base="xs:string">

<xs:enumeration value="inch"/>

<xs:enumeration value="cm"/>

</xs:restriction>

</xs:simpleType>

To ht best of my knowledge -- I dont think XML Schema supports your
conditional kind of validation.

I suggest taking a look at an alternative way i.e. XML Schematron
(Conditional Constraints are supported). Or you could think in terms of
XSLT itself i.e. write an XSLT that will be used as a way to validate.
However I am not sure if the this would be worth in the effort in the
overall context of what you are trying to validate here.
