categoryId  (integer) BIM property category ID, can be omitted (bcBimCategoryUser is used then); see Category Constants
---or---
categoryName  (string) BIM property category name, can be omitted( bcBimCategoryUser is used then), see Category Constants
if omitted, the all NameSpaces are automatically scanned to find the AttributeSet "name"

T or NIL, indicating whether the AttributeSet exists

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

the AttributeSet name/label is case-insensitive;
the BIM property category name is case sensitive;
if the NameSpace (as indirectly specified by categoryId resp. categoryName) does not exist, NIL is returned;
