Thanks J., newbie mistake... I get frustrated with the differences between
declaritive and procedural languages and I vent a little too much. Having
been away from XSLT for a time, then coming back to it, there are new
topics to learn every day. I thank you all for providing myself and the
larger community with your expertise and advice.

Wrong place to look, Xalan works as designed here. It is more an
issue about your understanding how XSLT works.
The src="url("$pic")" is copied through to the output
literally, exactly as the spec says. XSLT is not a macro language
where everything prefixed with a $ is substituted or somesuch.
If you want to have $pic evaluated in other places than select
and test attributes of certain XSLT elements, you have to say so
explicitely. In your case, the magic is named "attribute value template"
or short AVT (google it), and it means that parts of attribute values
which are enclosed in braces are evaluated as XPath expressions.
More specifically, use
<fo:external-graphic src="url("{$pic}")" ...
