/**
 * Class BaseFilter
 *
 * @property float  $x            = "<coordinate>" The minimum x coordinate for the subregion which restricts
 *           calculation and rendering of the given filter primitive.
 * @property float  $y            = "<coordinate>" The minimum y coordinate for the subregion which restricts
 *           calculation and rendering of the given filter primitive.
 * @property float  $width        = "<length>" The width of the subregion which restricts calculation and
 *           rendering of the given filter primitive. See filter primitive subregion. A negative value is an error. A
 *           value of zero disables the effect of the given filter primitive (i.e., the result is a transparent black
 *           image).
 * @property float  $height       = "<length>" The height of the subregion which restricts calculation and rendering of
 *           the given filter primitive. See filter primitive subregion. A negative value is an error (see Error
 *           processing). A value of zero disables the effect of the given filter primitive (i.e., the result is a
 *           transparent black image).
 * @property string $result       = "<filter-primitive-reference>" Assigned name for this filter primitive. If supplied,
 *           then graphics that result from processing this filter primitive can be referenced by an 'in' attribute on
 *           a subsequent filter primitive within the same 'filter' element. If no value is provided, the output will
 *           only be available for re-use as the implicit input into the next filter primitive if that filter primitive
 *           provides no value for its 'in' attribute. Note that a <filter-primitive-reference> is not an XML ID;
 *           instead, a <filter-primitive-reference> is only meaningful within a given 'filter' element and thus have
 *           only local scope. It is legal for the same <filter-primitive-reference> to appear multiple times within
 *           the same 'filter' element. When referenced, the <filter-primitive-reference> will use the closest
 *           preceding filter primitive with the given result.
 * @property string $in           = "SourceGraphic | SourceAlpha | BackgroundImage | BackgroundAlpha | FillPaint |
 *           StrokePaint | <filter-primitive-reference>" Identifies input for the given filter primitive. The value can
 *           be either one of six keywords or can be a string which matches a previous 'result' attribute value within
 *           the same 'filter' element. If no value is provided and this is the first filter primitive, then this
 *           filter primitive will use SourceGraphic as its input. If no value is provided and this is a subsequent
 *           filter primitive, then this filter primitive will use the result from the previous filter primitive as its
 *           input. {@link https://www.w3.org/TR/SVG11/filters.html#FilterPrimitiveInAttribute}

It seems like $child->getElement() targeting nstdio\svg\SVGElement::getElement() can also be of type object<DOMElement> or object<nstdio\svg\container\ContainerInterface>; however, nstdio\svg\util\KeyValueWriter::apply() does only seem to accept object<nstdio\svg\XMLDocumentInterface>, maybe add an additional type check?
