[fxtf-drafts] [filter-effects-1] Range limit missing from feSpecularLighting attribute "specularExponent" (#415)

BigBadaboom has just created a new issue for https://github.com/w3c/fxtf-drafts:

== [filter-effects-1] Range limit missing from feSpecularLighting attribute "specularExponent" ==
The SVG 1.1 spec says that specularExponent is clamped to the range: 1.0 to 128.0

See: https://www.w3.org/TR/SVG11/single-page.html#filters-feSpecularLightingSpecularExponentAttribute

> Exponent for specular term, larger is more "shiny". Range 1.0 to 128.0.
> If the attribute is not specified, then the effect is as if a value of 1 were specified.

*Note: this issue refers to the attribute of feSpecularLighting, **not** feSpotlight.*

However the corresponding definition in Filter Effects Module 1 does not mention this limit.
See: https://www.w3.org/TR/filter-effects/#element-attrdef-fespecularlighting-specularexponent

It is not clear whether this was deliberate or accidental. But I can't find any request for this change, or record in the Minutes of this change being made.

Is this an error?
