I have a stock element. This element has several child elements eg Currency, number and name. My problem is that I want (if possible to allow a choice re the type_of_stock. I want to limit it to either Equity or Bond - I have found two ways of doing this - either using enumeration or patterns. I have no preference as to which. However if they select BOND I want to force the user to input further elements eg the Interest_rate.
Helen,
The <xsd:choice> is worth looking at.
Something like,
<xsd:choice>
<xsd:element name="Equity" ... />
<xsd:sequence>
<xsd:element name="Bond" ... />
<xsd:element name="Interest_Rate" .../>
<!-- Whatever else you want to include with Bond -->
</xsd:sequence>
</xsd:choice>
