Summary

core-spec/expression_language.md describes PERCENTILE_CONT in two places, and they disagreed:

  • Normative definition (Percentile Functions, REQUIRED): PERCENTILE_CONT(p) WITHIN GROUP (ORDER BY expr) — the fraction is the argument, and the value goes in ORDER BY.
  • Ossie Standard column of the Tool Mappings table: PERCENTILE_CONT(x, 0.75) — positional, value first.

This PR corrects the illustrative mapping-table cell to match the normative definition. This is a documentation-consistency fix.

…documented syntax

The Tool Mappings table showed a positional PERCENTILE_CONT(x, 0.75)
in the Ossie Standard column, conflicting with the normative REQUIRED
definition PERCENTILE_CONT(p) WITHIN GROUP (ORDER BY expr). Correct the
illustrative cell to match the normative definition. Documentation
consistency only; no normative change.
