Resolved. Alas, I needed to add [passthrough] to my RewriteRule  
configuration:

   RewriteRule ^/etexts/id/(.*) /sandbox/semantic-web.cgi?id=$1  
[passthrough]

 From the mod_rewrite documentation:

   * 'passthrough|PT' (pass through to next handler)

   This flag forces the rewrite engine to set the uri field of the
   internal request_rec structure to the value of the filename
   field. This flag is just a hack to enable post-processing of the
   output of RewriteRule directives, using Alias, ScriptAlias,
   Redirect, and other directives from various URI-to-filename
   translators. For example, to rewrite /abc to /def using
   mod_rewrite, and then /def to /ghi using mod_alias:

     RewriteRule ^/abc(.*) /def$1 [PT]
     Alias /def /ghi

   If you omit the PT flag, mod_rewrite will rewrite uri=/abc/... to
   filename=/def/... as a full API-compliant URI-to-filename
   translator should do. Then mod_alias will try to do a
   URI-to-filename transition, which will fail. Note: You must use
   this flag if you want to mix directives from different modules
   which allow URL-to-filename translators. The typical example is
   the use of mod_alias and mod_rewrite.

I sincerely apologize for wasting people's time and bandwidth.
