Wrong. vl5 is not parented by sacroiliac.

Wrong. vl5's parent is humanoid_root.
<enumeration value="vl5" index="59" default="0.0028 1.0568 -0.0776" parent="
sacroiliac" loa="1" documentation="
https://en.wikipedia.org/wiki/Vertebral_column"/>
l_sternoclavicular's parent is vt1.
<enumeration value="l_sternoclavicular" index="91" default="0.0820 1.4488
-0.0353" parent="vc7" loa="2" documentation="
https://en.wikipedia.org/wiki/Sternoclavicular_joint"/>
r_sternoclavicular's parent is vt1.
<enumeration value="r_sternoclavicular" index="119" default="-0.0694 1.4600
-0.0330" parent="vc7" loa="2" documentation="
https://en.wikipedia.org/wiki/Sternoclavicular_joint"/>

vl5 is not a sibling of r_hip, clearly shown below.

vc7, l_sternoclavicular and r_sternoclavicular are siblings of the vt1
parent.

I believe that this is the report that sacroiliac is supposedly vl5's
parent.
Suggested change: Look for the parent to be the HAnimHumanoid element,
name='humanoid_root'.
Other schematron rules (vc7 should be vt1 in both cases):
<report test="$isHAnim2 and (@name='l_sternoclavicular') and
parent::HAnimJoint[not(@name='vc7')]" role="warning">
<
<name/>
DEF='
<value-of select="@DEF"/>
' name='
<value-of select="@name"/>
'/> has parent HAnimJoint name='
<value-of select="parent::HAnimJoint/@name"/>
' rather than expected parent name='vc7', recommend checking model
</report>
<report test="$isHAnim2 and (@name='r_sternoclavicular') and
parent::HAnimJoint[not(@name='vc7')]" role="warning">
<
<name/>
DEF='
<value-of select="@DEF"/>
' name='
<value-of select="@name"/>
'/> has parent HAnimJoint name='
<value-of select="parent::HAnimJoint/@name"/>
' rather than expected parent name='vc7', recommend checking model
</report>

Here are the three parent/child issues we have with schematron. I have
attached a more complete .x3d file.
<HAnimJoint DEF='hanim_l_sternoclavicular' name='l_sternoclavicular'/> has
parent HAnimJoint name='vt1' rather than expected parent name='vc7',
recommend checking model
<HAnimJoint DEF='hanim_vl5' name='vl5'/> has parent HAnimJoint
name='humanoid_root' rather than expected parent name='sacroiliac',
recommend checking model
<HAnimJoint DEF='hanim_r_sternoclavicular' name='r_sternoclavicular'/> has
parent HAnimJoint name='vt1' rather than expected parent name='vc7',
recommend checking model
You will find 'rather than expected parent' in 3 places in the schematron
log, stemming from misunderstandings of the standard LOA4 hierarchy.
I hope that this information, along with Joe's excellent writeup, will
prompt changes in the Schema, etc.
