Do you mean kernelMatrix? That is a really good question. I'd expect the following rule counts, even if it is not specified in SVG Filters directly:

<list-of-Ts>
(Where T is a type other than <string> and <family-name>.) A list consists of a separated sequence of values. Unless explicitly described differently, lists within SVG's XML attributes can be either comma-separated, with optional white space before or after the comma, or white space-separated.

White space in lists is defined as one or more of the following consecutive characters: "space" (U+0020), "tab" (U+0009), "line feed" (U+000A), "carriage return" (U+000D) and "form-feed" (U+000C).

The following is a template for an EBNF grammar describing the <list-of-Ts> syntax:

list-of-Ts ::= T
               | T comma-wsp list-of-Ts
comma-wsp  ::= (wsp+ ","? wsp*) | ("," wsp*)
wsp        ::= (#x20 | #x9 | #xD | #xA)
Within the SVG DOM, values of a <list-of-Ts> type are represented by an interface specific for the particular type T. For example, a <list-of-lengths> is represented in the SVG DOM using an SVGLengthList or SVGAnimatedLengthList object.

http://www.w3.org/TR/SVG/types.html#DataTypeNumber

So yes, I think leading spaces are not allowed for kernelMatrix as well.
