[basex-talk] unknown type error returned for xs:anySimpleType and xs:anyType

Hello,

I ran the following query using BaseX 9.3.3 command-line client: 'hello' instance of xs:anyAtomicType the result of the query is `true`.

But if I run this query: 'hello' instance of xs:anySimpleType an error "[XPST0051] Unknown type: xs:anySimpleType" is returned

Similarly, for the query: 'hello' instance of xs:anyType an error "[XPST0051] Unknown type: xs:anyType" is returned

Should xs:anySimpleType and xs:anyType be recognized?

Thank you, Yasir
