Because there is no top-level attribute declaration for 'begin' in
that schema.

Attribute declarations in attribute groups are not 'top-level',
because they're not guaranteed to be unique.

If I change the relevant part of your schema to read:

  <attribute name="begin" type="string"/>

  <attributeGroup name="timingAttrs">
   <attribute ref="begin" use="optional"/>
   <attribute name="dur" type="string" use="optional"/>
   <attribute name="end" type="string" use="optional"/>
   <attribute name="restart" use="default" value="always">
    <simpleType base="string">
     <enumeration value="always"/>
     <enumeration value="never"/>
     <enumeration value="whenNotActive"/>
   <attribute name="repeatCount" type="string" use="optional"/>
   <attribute name="repeatDur" type="string" use="optional"/>
   <attribute name="fill" use="default" value="remove">
    <simpleType base="string">
     <enumeration value="remove"/>
     <enumeration value="freeze"/>

it works fine.  (Now that I fixed a typo in the opportunistic
attribute validation code, that is :-)
