    337  *
    338  * For most basic types, the datatype+size descriptor is
    339  * straightforward. However for constructed types and strings,

    342  * specified in the 3 bits of the data size descriptor.
    343  *
    344  * TextString and URLString can be of size 2^{8, 16, 32} bytes
    345  * DataSequence and DataSequenceAlternates can be of size 2^{8, 16, 32}
    346  * The size are computed post-facto in the API and are not known apriori
