ISO/IEC Coding Guidelines: sub-figures and multiple graphics within a figure for ISO

[Intelligent2013]

Source: #190

For ISO: if the figure consists of multiple sub-figures , then each subfigure is captured as a separate <graphic> inside <fig>

vs. IEC:

If the figure consists of multiple sub-figures (each with their own caption), then each subfigure is captured as a separate <fig> inside <figure-group>.

Example:

<fig id="fig_C.2">
	<label>Figure C.2</label>
	<caption>
		<title>Stages of gelatinization</title>
	</caption>
	<graphic id="fig_C.2.1" xlink:href="...">
		<label>Figure C.2-1</label>
		<caption>
			<title>Initial stages: No grains are fully gelatinized (ungelatinized starch granules are visible inside the kernels)</title>
		</caption>
	</graphic>
	<graphic id="fig_C.2.2" xlink:href="...">
		<label>Figure C.2-2</label>
		<caption>
			<title>Intermediate stages: Some fully gelatinized kernels are visible</title>
		</caption>
	</graphic>
	<graphic id="fig_C.2.3" xlink:href="...">
		<label>Figure C.2-3</label>
		<caption>
			<title>Final stages: All kernels are fully gelatinized</title>
		</caption>
	</graphic>
</fig>
