VS-00.34-L-10002 is a component requirement written in the VS numbering system, which is used by the Swedish manufacturer for its corporate standards and is recognisable by the two groups of digits separated by a dot, followed by a letter that identifies the discipline and a number that identifies the document within it. A scheme of this kind is designed to be readable: a reader who knows it can tell from the designation which part of the company's technical documentation the document belongs to before opening it, and documents that share the leading group can be assumed to treat the same subject area. The requirement itself states the electromagnetic conditions applicable to a component and is cited in the engineering specification its supplier receives. The problem the document poses for a supplier is one of identification rather than of engineering: the number tells a reader who knows the system where the document belongs, but nothing about its content, so the only route to the requirement is through the engineering specification.
