          <xsd:documentation>The following is a description of the elements, types, and attributes that compose the IOS specific system characteristic items found in Open Vulnerability and Assessment Language (OVAL). Each item is an extension of the standard item element defined in the Core System Characteristic Schema. Through extension, each item inherits a set of elements and attributes that are shared amongst all OVAL Items. Each item is described in detail and should provide the information necessary to understand what each element and attribute represents. This document is intended for developers and assumes some familiarity with XML. A high level description of the interaction between the different tests and their relationship to the Core System Characteristic Schema is not outlined here.</xsd:documentation>

The value is a string and in the example 12.4(9)T0a the train identifier is 'T'.  The following explaination from Wikipedia should help explain the different train identifiers. Cisco IOS releases are split into several "trains", each containing a different set of features. Trains more or less map onto distinct markets or groups of customers that Cisco is targeting.  The 'mainline' train is designed to be the most stable release the company can offer, and its feature set never expands during its lifetime. Updates are released only to address bugs in the product. The previous technology train becomes the source for the current mainline train--for example, the 12.1T train becomes the basis for the 12.2 mainline. Therefore, to determine the features available in a particular mainline release, look at the previous T train release.  The 'T' (Technology) train, gets new features and bug fixes throughout its life, and is therefore less stable than the mainline. (In releases prior to Cisco IOS Release 12.0, the P train served as the Technology train.)  The 'S' (Service Provider) train, runs only on the company's core router products and is heavily customized for Service Provider customers.  The 'E' (Enterprise) train, is customized for implementation in enterprise environments.  The 'B' (broadband) train, support internet based broadband features.  The 'XA', 'Xb' ... (special functionality) train, needs to be documented.  There are other trains from time to time, designed for specific needs -- for example, the 12.0AA train contained new code required for Cisco's AS5800 product.</xsd:documentation>

Often a rebuild is compiled to fix a single specific problem or vulnerability for a given IOS version. For example, 12.1(8)E14 is a Rebuild, the 14 denoting the 14th rebuild of 12.1(8)E. Rebuilds are produced to either quickly repair a defect, or to satisfy customers who do not want to upgrade to a later major revision because they may be running critical infrastructure on their devices, and hence prefer to minimise change and risk.</xsd:documentation>

The mainline rebuild is just a regular rebuild release against the mainline operating system release (e.g. the branch of development that would typically be called "the trunk" that isn't associated with a train). Since there is no train identifier to stick the rebuild release after, they stick a alphabetic character inside the parens holding the maintenance release number. For example, 12.4(5b) is the second rebuild of the 12.4(5) maintenance release.</xsd:documentation>
