While this might be fixed in the latest version of PDE Build, in 3.5.x
a feature patch generates an exact match by the time it becomes an IU,
something like [3.5.0.vx-XrC,3.5.0.vx-XrC].  When I was using features
patches for Resources in e4, I had to massage the IUs after the fact
with XSL so that I wasn't constrained to specific Platform or RCP
features (useful when trying to apply to the 3.6 I builds :-)

  <xsl:template match="@range[../@name='org.eclipse.platform.feature.group']">
    <xsl:attribute name="range">[3.5.0,4.0.0)</xsl:attribute>
