> When using the | to create a set of alternative template matches the priority of the templates are set based on the lowest priority in the set of template matches apparently.
> e.g.: 
> <xsl:template match="otherPerson | person[lastName]"> MATCH 1...
> <xsl:template match="person"> MATCH 2...
> The default priority for MATCH 2 should be lower than the priority for MATCH 1 since it specifies a child element should be present.
> But when testing this, it results in MATCH 2.
> This is not correct according to the xslt specs [https://www.w3.org/TR/xslt-10/#dt-default-priority]
> A set of template matches behaves differently. 
> So e.g.:
> <xsl:template match="otherPerson"> MATCH 1...
> <xsl:template match="person[lastName]"> MATCH 1...
> <xsl:template match="person"> MATCH 2...
> This will select MATCH 1 when relevant as it should, because it has a higher priority than MATCH 2 now.
> See the attached project for the reproduction.
> The saxon implementation uses the expected matches, so it either does not have this bug or interprets the spec differently.
