    <thetext>http://www.w3.org/TR/filter-effects-1/#FilterUnitsAttribute says:

&quot;If filterUnits is equal to objectBoundingBox, then x, y, width, height represent fractions or percentages of the bounding box on the referencing element (see object bounding box units).&quot;

Now, if we take an example of a valid &lt;length&gt; for the x attribute, say &quot;47em&quot;, how should that be interpreted in the case of filterUnits=&quot;objectBoundingBox&quot;?

I think the author&apos;s expection might be that 47em is kept as just that, but actually what happens is that it gets computed into user units and then taken as a fraction of the boundingbox.

Therefore I&apos;d like to ask that the behavior is clarified such that it becomes more obvious that this happens.</thetext>

    <thetext>As discussed in the FX meeting (http://www.w3.org/2015/02/10-fx-irc) there is nothing that we need to change in Fitler Effects. CSS specifies this case sufficiently.</thetext>
