For example:

para          → 0
h:*           → -0.25
*             → -0.25
node()        → -0.5
contents/para → 0.5
contents/*    → 0.5

You can adjust the priority to get what you want with a 'priority' attribute.

<xsl:template match="h:*" priority="1">
...
</xsl:template>

If two templates match and they have the same priority, it is an error--but the processor can recover and choose the last template in document order.
