+The general syntax used to describe requests, replies, errors, events, and
+compound types is:
+</para>
+<para>
+<!-- .LP -->
+<literallayout class="monospaced">

+Each encode-form describes a single component.

+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i 2.5i -->
+<!-- .ta 1i 1.5i 2.5i -->
+N TYPE name
+</literallayout>
+N is the number of bytes occupied in the data stream,
+and TYPE is the interpretation of those bytes.
+For example,
+</para>
+<para>
+<!-- .LP -->
+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i -->
+<!-- .ta 1i 1.5i -->

+<!-- .ta 1i 1.5i 2.5i -->
+N value name
+</literallayout>
+The value is always interpreted as an N-byte unsigned integer.
+For example,
+the first two bytes of a Window error are always zero (indicating an
+error in general) and three (indicating the Window error in particular):
+</para>

+<!-- .LP -->

+N name
+ value1 Name1
+ ...
+ valueI NameI
+</literallayout>
+The value is always interpreted as an N-byte unsigned integer.
+Note that the size of N is sometimes larger than that strictly required
+to encode the values.
+For example:
+</para>
+<para>
+<!-- .LP -->
+<literallayout class="monospaced">

+N TYPE NAME

+ ...

+The alternative values are guaranteed not to conflict with the encoding

+</literallayout>
+the encode-form is:

+<para>
+<!-- .LP -->
+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i 2i 2.5i -->
+<!-- .ta 1i 1.5i 2i 2.5i -->
+N BITMASK value-mask
+ mask1 mask-name1
+ ...
+ maskI mask-nameI
+</literallayout>
+The individual bits in the mask are specified and named,
+and N is 2 or 4.
+The most-significant bit in a BITMASK is reserved for use in defining
+chained (multiword) bitmasks, as extensions augment existing core requests.
+The precise interpretation of this bit is not yet defined here,
+although a probable mechanism is that a 1-bit indicates that another N bytes
+of bitmask follows, with bits within the overall mask still interpreted
+from least-significant to most-significant with an N-byte unit, with N-byte units
+interpreted in stream order, and with the overall mask being byte-swapped
+in individual N-byte units.
+</para>
+<para>
+<!-- .LP -->
+For LISTofVALUE encodings, the request is followed by a section of the form:
+</para>
+<para>
+<!-- .LP -->
+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i -->
+<!-- .ta 1i 1.5i -->
+VALUEs
+ encode-form
+ ...
+ encode-form
+</literallayout>
+listing an encode-form for each VALUE.
+The NAME in each encode-form keys to the corresponding BITMASK bit.
+The encoding of a VALUE always occupies four bytes,
+but the number of bytes specified in the encoding-form indicates how
+many of the least-significant bytes are actually used;
+the remaining bytes are unused and their values do not matter.
+</para>
+<para>
+<!-- .LP -->
+In various cases, the number of bytes occupied by a component will be specified
+by a lowercase single-letter variable name instead of a specific numeric
+value, and often some other component will have its value specified as a
+simple numeric expression involving these variables.
+Components specified with such expressions are always interpreted
+as unsigned integers.
+The scope of such variables is always just the enclosing request, reply,
+error, event, or compound type structure.
+For example:
+</para>
+<para>
+<!-- .LP -->
+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i 2i 2.5i -->
+<!-- .ta 1i 1.5i 2i 2.5i -->
+2 3+n request length
+4n LISTofPOINT points
+</literallayout>
+For unused bytes (the values of the bytes are undefined and do not matter),
+the encode-form is:
+</para>
+<para>
+<!-- .LP -->
+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i 2i 2.5i -->
+<!-- .ta 1i 1.5i 2i 2.5i -->
+N unused
+</literallayout>
+If the number of unused bytes is variable, the encode-form typically is:
+</para>
+<para>
+<!-- .LP -->
+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i 2i 2.5i -->
+<!-- .ta 1i 1.5i 2i 2.5i -->
+p unused, p=pad(E)
+</literallayout>
+where E is some expression,
+and pad(E) is the number of bytes needed to round E up to a multiple of four.

+<!-- .LP -->
+<literallayout class="monospaced">
+<!-- .TA 1i 1.5i 2i 2.5i -->
