tiny.spec does not match the syntax (define without signature)

[Trolldemorted]

I have written a parser for L3, but it fails to parse the tiny spec because it has this define:

acjf3.github.io/l3/tiny.spec

Lines 137 to 139 in 7f0dd08

	define ReservedInstr = #Reserved

The manual (B, "Definitions") states:

<definition> ::= 'define' <define>
               | 'component' <component>
               | <function>
<define> ::= <ast> <define-sig> '=' <block>

where <define-sig> is not optional, so my parser is correct when it says that the tiny spec is invalid.

Is this a bug in the tiny spec or in the language specification?
