What each generator documents about marking its output

Which columns each row actually fills

Rows here come in two shapes. One fills the commercial columns and leaves the file column empty; the other fills the file column and leaves the commercial ones empty. No row fills all four. As of 2026-09-22.

The two shapes a row takes, and what fills each oneA grid-read row carries a tier, a price and a control mechanism, with the file column empty. A row read from a card or a reference carries a named standard and sometimes a named reader, with the tier and control columns empty. No row on this register carries both sets.Read from a gridRead from a card or referenceCrossing pointA tier, often with a priceNothing publishedControlA plan benefitNothing published, or a request fieldFile contentsNothing publishedA named standard, sometimes a readerThe mark itselfNamed in a word or twoSometimes describedNo entry here fills both columns of this figure

Inclusion rule. Entries chosen to illustrate the two shapes a row can have, one from the grid-read group and two from the group read from technical documents. Order. Alphabetical by generator name.

1Two shapes, and nothing in between

The first shape: a crossing point, a price, a control mechanism, and not documented for file contents. That is what a pricing grid produces, because a grid is built to make an upgrade obvious and a provenance manifest is not something anybody upgrades to buy.

The second shape: a named standard, sometimes a named reader, sometimes a described mark, and not documented for the crossing point and the control. That is what a system card, a service card or an interface reference produces, because none of those documents has a reason to discuss a subscription.

2The split follows the document, not the company

Several of the companies in the second group sell subscriptions, and several in the first group publish developer documentation. The shape of a row is decided by which page the marking statement happens to live on, which is a fact about internal publishing practice rather than about candour or engineering.

That makes the shape of a row a usable signal about who a vendor was writing for. A company whose only marking statement is on a price list has treated marking as a packaging question; one whose only statement is on a card has treated it as a safety question. Neither has treated it as both.

3What a reader wanting both is looking for

Nothing on this register. No entry publishes a crossing point and a named standard and a described mark, and there is no reason to expect one until a vendor writes a page addressed to publishers rather than to buyers or reviewers.

The nearest approach is an entry whose interface reference specifies the text and corner of a visible stamp and names no metadata field at all: one document, opposite levels of detail on the frame and the file. Reading the register by shape makes that gap the finding rather than an accident of which pages were read.

Every row above is read from the vendor page named beside it, on 2026-09-22. The same values in register form are on the support table, the rule for this column is on the machine-readable marking column page, and what may fill a cell at all is on the what earns a row page. Other findings: two prices for one tier, licences and marks.
