For <feComposite>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feConvolveMatrix>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feDiffuseLighting>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feDisplacementMap>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feDropShadow>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feFlood>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feFuncA>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feFuncB>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feFuncG>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feFuncR>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feGaussianBlur>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feImage>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feMerge>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feMergeNode>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feMorphology>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feOffset>, x defines the minimum x coordinate for the rendering area of the primitive.

For <fePointLight>, x defines the x location for the light source in the coordinate system defined by the primitiveUnits attribute on the <filter> element.

For <feSpecularLighting>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feSpotLight>, x defines the x location for the light source in the coordinate system defined by the primitiveUnits attribute on the <filter> element.

For <feTile>, x defines the minimum x coordinate for the rendering area of the primitive.

For <feTurbulence>, x defines the minimum x coordinate for the rendering area of the primitive.

For <filter>, x defines the x coordinate of the upper left corner for the rendering area of the filter.

For <foreignObject>, x defines the x coordinate of the upper left corner of its viewport.

For <glyphRef>, x defines the x-axis coordinate of the glyph.

For <image>, x defines the x coordinate of the upper left corner of the image.

For <mask>, x defines the x coordinate of the upper left corner of its area of effect. The exact effect of this attribute is influenced by the maskUnits attribute.

For <pattern>, x defines the x coordinate of the upper left corner of the tile pattern. The exact effect of this attribute is influenced by the patternUnits and patternTransform attributes.

For <rect>, x defines the x coordinate of the upper left corner of the shape.

For <svg>, x defines the x coordinate of the upper left corner of its viewport.

For <text>, if it contains a single value, x defines the x coordinate where the content text position must be placed. The content text position is usually a point on the baseline of the first line of text. The exact content text position is influenced by other properties, such as text-anchor or direction.

If it contains multiple values, x defines the x coordinate of each individual glyph from the text. If there are fewer values than glyphs, the remaining glyphs are placed in line with the last positioned glyph. If there are more values than glyphs, the extra values are ignored.
