This example points to a glyph element with the identifier flig like the following:
<glyph xml:id="flig">
<!-- here we describe the particular f-ligature intended -->
</glyph>
Example
<g ref="#per">per</g>
The medieval brevigraph per could similarly be considered as an individual glyph, defined in a glyph element with the identifier per like the following:
<glyph xml:id="per">
<!-- ... -->
</glyph>
