text

For <text>, if it contain a single value, y defines the y coordinate on where the content text position must be placed.

If there are multiple values, y defines the y coordinate of each individual glyph from the text. If there are less values than glyphes, the remaining glyphes are placed in the continuity of the last positioned glyph. If there are more values than glyphes, extra values are ignored.
