            Bug ID: 29979
           Summary: [XSLT30] Imposing limits on the priority attribute
           Product: XPath / XQuery / XSLT
           Version: Candidate Recommendation
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: minor
          Priority: P2
         Component: XSLT 3.0
          Assignee: mike@saxonica.com

  Target Milestone: ---

We have recently allowed processors to impose limits on version numbers for
packages. Another aspect of the spec that has unlimited range is the priority
attribute for templates.

I propose we do something similar as we did with versioning, except we can
choose a more natural limit here, since it is only one number. I propose a rule
something like the following:

<proposal>
Implementations may impose limits on the range of allowed decimal values and
its precision, but it *must* be no less than 16 digits precision.
</proposal>

This range follows the minimal range XSD 1.1 imposes.

I don't propose to use a new error for this, implementations can re-use error
XTSE0020 (invalid attribute value).
