Nathan created XALANJ-2824:
------------------------------

             Summary: Template alternative with | do not use correct priorities
                 Key: XALANJ-2824
                 URL: https://issues.apache.org/jira/browse/XALANJ-2824
             Project: XalanJ2
          Issue Type: Bug
      Security Level: No security risk; visible to anyone (Ordinary problems in Xalan projects.  Anybody can view the issue.)
          Components: SAX, transformation, Xalan
    Affects Versions: 2.7.3
            Reporter: Nathan
         Attachments: reproduction-priorities.zip

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.
