SVG paths are an extension of PostScript paths - these are a sequence
of disjoint subpaths. You can have as many such subpaths as you like.

However, they are always rendered as 'one thing' which is where the
fillRule (evenodd or nonzero) and direction of the subpaths comes into
play to decide which parts are filled and which parts are not.

A good illustrated example is given here:

Warmest Regards,
