Constraint on WFS feature: what does this error mean and how to solve it?

Hi everyone,

I am trying to extract some features from a WFS, but it is giving me an error.

I'm reading from: https://geodata.nationaalgeoregister.nl/kadastralekaart/wfs/v4_0?service=WFS&version=2.0&request=GetCapabilities

And this is the filter expression I use:

<Filter>

<Or>

<PropertyIsEqualTo>

<PropertyName>AKRKadastraleGemeenteCodeWaarde</PropertyName>

<Literal>WMV00</Literal>

</PropertyIsEqualTo>

<PropertyIsEqualTo>

<PropertyName>AKRKadastraleGemeenteCodeWaarde</PropertyName>

<Literal>KMN01</Literal>

</PropertyIsEqualTo>

<PropertyIsEqualTo>

<PropertyName>AKRKadastraleGemeenteCodeWaarde</PropertyName>

<Literal>ZDM01</Literal>

</PropertyIsEqualTo>

<PropertyIsEqualTo>

<PropertyName>AKRKadastraleGemeenteCodeWaarde</PropertyName>

<Literal>KOO00</Literal>

</PropertyIsEqualTo>

<PropertyIsEqualTo>

<PropertyName>AKRKadastraleGemeenteCodeWaarde</PropertyName>

<Literal>ASD01</Literal>

</PropertyIsEqualTo>

<PropertyIsEqualTo>

<PropertyName>AKRKadastraleGemeenteCodeWaarde</PropertyName>

<Literal>WZN00</Literal>

</PropertyIsEqualTo>

<PropertyIsEqualTo>

<PropertyName>AKRKadastraleGemeenteCodeWaarde</PropertyName>

<Literal>ZDK00</Literal>

</PropertyIsEqualTo>

</Or>

</Filter>

The translation fails and gives me this message:

line: 10 column: 4855 message: '<' character cannot be used in attribute value 'previous'; use &lt; instead'

What can I do to solve this error and where can I even look and go to to see attribute value 'previous'? I cannot find any attribute with this value anywhere.

Thanks for the help folks!
