How to add data to each point in a track

[naa...@gmail.com]

I have a placemark:

<Placemark>

<name>Rabet</name>

<description>This is the description of a path - Rabet</description>

<styleUrl>#msn_ylw-pushpin</styleUrl>

<LineString>

<tessellate>1</tessellate>

<coordinates>

12.40037967162732,51.34576810913315,0 12.40025166816521,51.34453744792744,0 12.40102503466703,51.34415421608146,0 12.40235063799527,51.34342321177011,0 12.40373630368036,51.34274867716953,0 12.40415014174027,51.34267271164675,0 12.40585313639402,51.34263529049948,0 </coordinates>

</LineString>

</Placemark>

I want to add information to each point  , something like this:

<Placemark>

    <Point>

<name>Spot 2</name>

<description>12 May 2011, 2.3g nugget</description>

        <coordinates>144.253,-36.6632,0</coordinates>

    </Point>

    <Point>

<name>Spot 3</name>

<description>6 June 2011, 5.6g nugget</description>

        <coordinates>144.2891,-36.6894,0</coordinates>

    </Point>

    <Point>

   <name>Spot 5</name>

<description>28 June 2011, 4.1g nugget</description>

        <coordinates>144.2344,-36.6907,0</coordinates>

    </Point>

</Placemark>

but now google maps doesnt recognize is as a track. 

how can I add information to each point properly?
