Ordered lists as [N.x], new code based on CSS for [x]

I have had help from the mailforum css-disuss.org, but it seems dead now. And I couldn’t find another CSS forum either(?)

I have had this ordered list for years now:

[1] Reference 1 in here
[2] Reference 2 in here
[3] Reference 3 in here
[4] Reference 4 in here

but I now want this, where I can add ‘4’ in Text mode like “chapter:4;”

[4.1] Reference 1 in here
[4.2] Reference 2 in here
[4.3] Reference 3 in here
[4.4] Reference 4 in here

The code that does the first (courtesy Chris Rockwell) is the below. Can anybody help me with adding a constant like ‘4’ above (at several places in the same document, like ‘3’ at another place. I’m sorry I haven’t coded CSS to any depth like that before. Here is what I have:

ol.ol_href {
    list-style-type: none;
    counter-reset: section;
    padding-left: 0;
}
ol.ol_href li {
    display: table-row
}
ol.ol_href li:before {
    counter-increment: section;
    content: "[" counter(section) "] ";
    padding-right: 1em;
    display: table-cell;
}

and the usage in Text is. The ids I add by hand in Text:

<ol class="ol_href">
 	<li id="Ref_01">Reference 1 in here</li>
 	<li id="Ref_02">Reference 2 in here</li>
 	<li id="Ref_03">Reference 3 in here</li>
 	<li id="Ref_04">Reference 4 in here</li>
</ol>

I would end up with something like this with the new scheme, also added by hand in Text:

<ol class="ol_href">
 	<li id="Ref_04_01">Reference 4.1 in here</li>
 	<li id="Ref_04_02">Reference 4.2 in here</li>
 	<li id="Ref_04_03">Reference 4.3 in here</li>
 	<li id="Ref_04_04">Reference 4.4 in here</li>
</ol>
