It creates a copy of an SVG file to allow customization of SVG symbol settings in QGIS.

param (fill),param (fill-opacity),param (outline),param (outline-opacity),param (outline-width).Before modification:
<path
style="fill:none ; stroke:#000000 ; stroke-width:0.4"
/>

After modification:
<path
style="fill:none ; stroke:param(outline) #000000 ; stroke-width:param(outline-width) 0.4"
/>
