<!-- The container for XBRL GL, accountingEntries, is not the root of an XBRL GL file - the root, as with all XBRL files, is xbrl. This means that a single XBRL GL file can store one or more virtual XBRL GL files, through one or more accountingEntries structures with data inside. The primary key to understanding an XBRL GL file is the entriesType. A single physical XBRL GL file can have multiple accountingEntries structures to represent both transactions and master files; the differences are signified by the appropriate entriesType enumerated values. This is especially important in a representation of this kind. A file creator can create a single physical file but have information about the customers in one accountingEntries section and in information about the invoices in another referencing only the customer number, thereby reducing the duplicated information (customer name, address, etc.) in the file resulting in smaller file sizes. -->

<gl-cor:documentInfo>

<!-- This field, entriesType, provides the automated guidance on the purpose of the XBRL GL information.

<!-- As noted, when illustrating details on a form/document, individual line are represented using entryDetail which must be held together by entryHeaders - one primary amount per entryDetail line. However, you can list different accounts within the same entryDetail line that are associated with that amount. For example, if you capitalize for US GAAP and expense for IFRS, you can have multiple account structures within one entryDetail section. The generic nature of XBRL GL means that much of the information that is common to each line, such as the customer, or the document attributes, must be repeated on each detail line, or be entered into one of the lines with an understanding that it is common to all. -->

<!-- Amounts in XBRL GL when representing invoices and details can be tricky. In the simplest sense, the amount at the line level can simply represent the extended amount of the line (the cost per is within the measurable structure). Sales tax, freight and other non-line items can be represented with a measurable item representing those items, or with a GL account representing those items. Should the user choose to represent the "total" amount, the individual lines or the total can be notated with the amountMemo to minimize the risk of amounts being double-counted if the invoices will later be turned into accounting entries.-->

It may be confusing that the customer must be identified for each line of an invoice. Why isn't the customer customer at the Header level? The answer - the generic nature of XBRL GL means it must accommodate both detail and summary style of entry. Rather than duplicate the identifier structure at both header and detail level, it is at the detail level.-->
