Steve,

The variable length encoding of the basic encoding rules can only be
used for constructed types.  X.209(88) (== ISO 8825:1987) 6.3.2 reads:

    A sender shall

    a)  use the definite form if the encoding is primitive;

    b)  use either the definite form or the indefinite form, a sender's
        option, if the encoding is constructed and all immediately
        available;

    c)  use the indefinite form if the encoding is contructed and is not
        all immediately available.

Since the constructed encodings ultimately have objectes with primitive
encoding as their constituents, your problem never arises.

In your particular case, you can choose the primitive encoding:

        03 06 00 09 00 00 00 09
        -- -- -- --------------
         |  |  |              |
         |  |  |              +-- contents
         |  |  +----------------- number of residual bits in last octet
         |  +-------------------- definite form, length of content
         +----------------------- universal, primitive, bit string

or constructed:

        23 80 03 06 00 09 00 00 00 09 00 00
        -- -- ----------------------- -----
         |  |                       |     |
         |  |                       |     +-- end of contents marker
         |  |                       +-------- contents of constructed
         |  |                                 encoding (see above!)
         |  +-------------------------------- indefinite form
         +----------------------------------- universal, constructed,
                                              bit string

Hope this helps.
