Write a small Perl script to pack them into an SGML document (DTD & instance
could be defined in the same file) and call (sgml-parse) on that file. I
believe Jade will see entities in the catalog, and anyway you can use a
(fixed) system-id.

Say something like
<!DOCTYPE environment [

<!element environment O O (variable*) >
<!element variable - O EMPTY >
<!attlist variable
    name ID #REQUIRED
    value CDATA #REQUIRED
>
]
>

<variable 
    name = "PATH" 
    value = "/bin:/usr/bin"
>
<variable
    name = "GENERATE_TOC"
    value = "1"
>

(define *environment-parameters-file* "environment.dsssl")

(define (getenv var)
    (attribute-string
        "value"
        (element-with-id
            var
            (sgml-parse *environment-parameters-file*)
        )
    )
)

I gave up on passing parameters to Jade long ago, but your question
triggered something somewhere.
