Your welcome Doug,
I am always discovering new things with CSS and coding. Your confusion
prompted me to do a test case so I could understand and hopefully
explain what the specs are suggesting. :-)
<http://css-class.com/test/css/visformatting/vertical-align.htm>
Test 1 and 3 with vertical-align:middle does indicate that the line box
line-height [1] is calculated after the vertical alignment is calculated.
