Fix misleading Validation Summary numbers in HTML report

[dragosprisaca]

Problem

The "Validation Summary" section in the HTML validation report displays numbers that don't add up, confusing users:

Total Requirements:        65
Applicable Requirements:   56
Requirements Passed:       54 of 54   ← denominator (54) ≠ Applicable (56)
Requirements Failed:        0 of 54   ← same mismatched denominator
Tests Failed:              39         ← 39 tests fail but 0 requirements fail?
Overall Result:            Pass

Three issues:

1. WARNING counted as PASS — WARNING requirements are silently included in "Requirements Passed" (count(PASS or WARNING)), giving users no visibility into warnings.
2. Denominator mismatch — the "of N" denominator only counts PASS + FAIL + WARNING, excluding INFORMATIONAL requirements. This doesn't match "Applicable Requirements" which includes them.
3. No breakdown — users cannot tell how many requirements had warnings vs. informational results without scrolling through the full report body.

Root Cause

In decima-xml/src/main/resources/xsl/result.xsl (lines 338–353):

• "Requirements Passed" numerator: count(PASS or WARNING) — lumps WARNING into passed
• Denominator for both Passed/Failed: count(PASS or FAIL or WARNING) — excludes INFORMATIONAL
• No separate lines for WARNING or INFORMATIONAL counts

Proposed Solution

Update the XSLT summary section to:

• Count only PASS (not WARNING) for "Requirements Passed"
• Use the Applicable Requirements count as the denominator for all lines (consistent with the "Applicable Requirements" row)
• Add conditional "Requirements Warning" line (shown only when warnings exist)
• Add conditional "Requirements Informational" line (shown only when informational results exist)

Expected result after fix:

Total Requirements:              65
Applicable Requirements:         56
Requirements Passed:             51 of 56
Requirements Warning:             3 of 56
Requirements Informational:       2 of 56
Requirements Failed:              0 of 56
Tests Failed:                    39
Overall Result:                  Pass

Now 51 + 3 + 2 + 0 = 56 = Applicable Requirements. All numbers add up and each status type is visible.

Files to Modify

• decima-xml/src/main/resources/xsl/result.xsl — update the Validation Summary <dl> section (~25 insertions, 3 deletions)

Notes

• The pie chart already separates PASS, WARNING, and INFORMATIONAL as distinct categories — this fix makes the text summary consistent with the chart.
• The NOT_TESTED and NOT_IN_SCOPE exclusion logic (controlled by $ignore-not-tested-results and $ignore-outofscope-results parameters) is preserved.
