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.
