David Marston commented on XALANJ-1981:
---------------------------------------

Luckily for you, the example you gave can be
accomplished with one declaration:
<xsl:key name='foo'
match='someElement|someOtherElement'
use='@name'/> 

In general, it would be desirable to allow
multiple xsl:key declarations of the same name to
be merged, because then you can have
<xsl:key name='foo' match='x' use='@ex' />
<xsl:key name='foo' match='y' use='@why' />
and the @ex will only index the x elements, not the
y elements, while the @why will only index the y
elements. The spec allows this behavior.

> multiple <xsl:key> elements for the same index does not work

> If there are two <xsl:key> elements for the same index in a stylesheet, then xalan 
> appears to ignore the second one.
> eg:
> <xsl:key name='foo' match='someElement' use='@name'/>
> <xsl:key name='foo' match='someOtherElement' use='@name'/>
> The key will only contain entries for someElement, not for someOtherElement.
