Hello. I'm trying to implement simple raid frames. Here's what I've come up with so far:

XML:

<Ui xmlns="http://www.blizzard.com/wow/ui/">
  <Frame name="MyFrames_UnitTemplate" inherits="SecureUnitButtonTemplate" virtual="true">
    <Size x="36" y="36"/>
    <Layers>
      <Layer level="OVERLAY">
        <Texture>
          <Color r="0" g="0" b="0"/>
        </Texture>
        <FontString parentKey="name" inherits="GameFontHighlight" text="Name"/>
      </Layer>
    </Layers>
    <Attributes>
      <Attribute name="type1" type="string" value="target"/>
    </Attributes>
  </Frame>
  
  <Frame name="MyFrames_SecureGroupTemplateHeader" parent="UIParent" inherits="SecureGroupHeaderTemplate">
    <Anchors>
      <Anchor point="TOP"/>
    </Anchors>
    <Attributes>
      <Attribute name="showParty" type="boolean" value="true"/>
      <Attribute name="showRaid" type="boolean" value="true"/>
      <Attribute name="showPlayer" type="boolean" value="true"/>
      <Attribute name="showSolo" type="boolean" value="true"/>
      <Attribute name="maxColumns" type="number" value="8"/>
      <Attribute name="unitsPerColumn" type="number" value="5"/>
      <Attribute name="columnAnchorPoint" type="string" value="TOP"/>
      <Attribute name="point" type="string" value="LEFT"/>
      <Attribute name="template" type="string" value="MyFrames_UnitTemplate"/>
      <Attribute name="templateType" type="string" value="Button"/>
      <Attribute name="columnSpacing" type="number" value="1"/>
    </Attributes>
  </Frame>
</Ui>

LUA:

MyFrames_SecureGroupTemplateHeader:SetAttribute("initialConfigFunction", [=[
  print("icf", self:GetName())
  self:SetAttribute("refreshUnitChange", [[
    print("ruc", self:GetName(), self:GetAttribute("unit"))
    --self.name:SetText(UnitName(self:GetAttribute("unit")))
  ]])
]=])
 
MyFrames_SecureGroupTemplateHeader:Show()

It works with static label, but I'm struggling to set name dynamically. I've commented line that does not work. As far as I understood, self refers to frame handle and this frame handle does not have "name" key (which I expected to be set from XML parentKey attribute). I tried to use self:GetFrameRef("name"), but it returns null. I guess I have to register it earlier, but I can't figure out how do I do that. UnitName is not available either, so I'm further confused atm. I guess, I'm doing something seriously wrong. If possible, I prefer to keep XML for UI layouts instead of coding it all with Lua. Also, if possible, it should work in combat (so people entering/leaving raid won't brake frames, that's why I'm using SecureGroupHeaderTemplate).
