Re: [xsl] find unique codes

Yes. You can use two xsl:key elements with the same name, as follows:

<xsl:key name="extended-attrs"
         match="ExtendedAttributeDefinition"
         use="@ExtendedAttributeDefinitionCode" />
<xsl:key name="extended-attrs"
         match="ExtendedAttribute"
         use="@ExtendedAttributeCode" />

If ExtendedAttributeDefinition elements can't have
ExtendedAttributeCode attributes, and ExtendedAttribute elements can't
have ExtendedAttributeCode attributes, then this is exactly the same
as:

<xsl:key name="extended-attrs"
         match="ExtendedAttributeDefinition | ExtendedAttribute"
         use="@ExtendedAttributeDefinitionCode |
              @ExtendedAttributeCode" />

but it's easier to see what's going on with the separate keys.

Cheers,

Jeni
