How check string starts with number count in XSLT

Input:

<para>
    <text>1. this a paragaraph1</text>
    <text>12. this a paragaraph2</text>
    <text>2. this a paragaraph2</text>
    <text>this a paragaraph3</text>
</para>

My current output:

<result>
    <para type="number">1. this a paragaraph1</para>
    <para type="number">12. this a paragaraph2</para>
    <para type="number">2. this a paragaraph2</para>
    <para type="not number">this a paragaraph3</para>
</result>

Output should be:

<result>
    <para type="number">1. this a paragaraph1</para>
    <para type="number double">12. this a paragaraph2</para>
    <para type="number">2. this a paragaraph2</para>
    <para type="not number">this a paragaraph3</para>
</result>

Explanation of the logic:

You can see para/text has a string. Some of them are starting with numbers (1. , 12. ) then . and space. At that time para/@type must be number. If the count of that number is 1 @type should be number. If the count of that number is 2 @type should be number double. You can see the example.

Tried code:

<xsl:template match="text">
    <xsl:choose>
        <xsl:when test="matches(.,'^[0-9]+\. ')">
            <para type="number">
                <xsl:value-of select="."/>
            </para>
        </xsl:when>
        <xsl:otherwise>
            <para type="not number">
                <xsl:value-of select="."/>
            </para>
        </xsl:otherwise>
    </xsl:choose>
</xsl:template>
    
<xsl:template match="para">
    <xsl:apply-templates/>
</xsl:template>

I am using XSLT 2.0.

How about:

<xsl:template match="text">
    <xsl:copy>
        <xsl:attribute name="type">
            <xsl:choose>
                <xsl:when test="matches(., '^\d{2}\. ')">double</xsl:when>
                <xsl:when test="matches(., '^\d\. ')">number</xsl:when>
                <xsl:otherwise>not number</xsl:otherwise>
            </xsl:choose>
        </xsl:attribute>
        <xsl:value-of select="."/>
    </xsl:copy>
</xsl:template>
