Sorry, I forgot to explain the meaning of this "loose attachment" term.
It is basically attachment(s) that didn't strapped into the document (e.g. You can take it out from the document to be viewed separately). This kind of attachment mostly consists of map, or some other document too large to be fit into the document.

Maybe another similar term is "lembaran lepas" or handout.

Hope this explanation helps you a lot :)
Good luck ^^

Yes, you can translate the term above into loose insert(s) too.

In Bahasa Indonesia, we didn't define the term "lampiran" (attachment) as something attached / bound (binded) / strapped / stuck onto another thing.

More likely something that comes with the main object, but not definitely need to be "attached".


You can find the definition in here: (in Bahasa Indonesia)
http://www.artikata.com/arti-369730-lampiran.html

noun
1. sesuatu yg dilampirkan; tambahan pd surat (lamaran, keputusan, dsb);
source: kbbi3

2. lembar tambahan pd surat kabar
source: kbbi3


Lost in translation :)

The attachment could be part of other document; it is simply impossible to include it without attaching its parent document.

Another case is when the attachment is large, or even larger than the document to which it has to be attached.

Why it is called lampiran lepas? One good reason is when the main document clearly claims that the attachment(s) are to be considered as integral and inseparable part. Legalese stuff.

In electronic document, the concept of external attachment is easily implemented through linking and addressing.

You are correct that "lampiran lepas" have separate covers. "Lampiran lepas" are "annexes". It is common in consulting services to produce reports plus annexes.

An appendix is a part of a document that doesn't really have a place within the body or is an operational tool that is referenced in the document an appendix and should not be able to stand alone. If it is you should consider including it directly into the document. An annex is another document all together (often called stand alone) but has direct relevance to your document.

This would get round the problem of unattached attachments :)
