What regular expressions should I use for numbers, floating point numbers, and numbers with a logical operator in the XSD schema?

Question

Database design

Input object height data (meters):
<0.05
0.05
0.1
0.2
...
5
7
8
9
10
>10
Sample code

<xs:simpleType name="ВысотаОбъекта">
    <xs:restriction base="xs:string">
        <xs:pattern value=".......регулярные выражения???"/>
    <xs:documentation>&lt;0,05<xs:documentation/>
    <xs:documentation>0,05<xs:documentation/>
    <xs:documentation>0,1<xs:documentation/>
    <xs:documentation>0,2<xs:documentation/>
    <xs:documentation>...<xs:documentation/>
    <xs:documentation>9<xs:documentation/>
    <xs:documentation>10<xs:documentation/>
    <xs:documentation>=&gt;11"<xs:documentation/>
    </xs:restriction>
</xs:simpleType>

Alternatively:
[0.05-70]|comparison operator and number??? - but I can't figure out how to specify that a number can go with an operator or a floating point number can go with an operator.
Question:
That is . input integers, floating point numbers, logical operators with integers, logical operators with a floating point number.
Can you please tell me which regular expression is suitable for processing the specified data?
