---or---
categoryName  BIM property category name as string, can be omitted (bcBimCategoryUser is used then), see Category Constants

if omitted, the "User" NameSpace is automatically used to search for all AttributeSets

T or NIL, indicating success or failure

Example

(bim:create-attributeset "---testName---" "---testLabel---" T)  T
(bim:has-attributeset "---testName---")  T
(bim:delete-attributesets)  T
(bim:has-attributeset "---testName---")  NIL

the BIM property category name is case sensitive;
if the NameSpace (as indirectly specified by categoryId resp. categoryName) does not exist, it will be automatically created, as a visible NameSpace
