[Open-scap] Proper use of oscap xccfg generate guide

[Shawn Wells]

Within the SSG project we have several profiles:
> $ grep "<Profile" output/unlinked-rhel6-xccdf.xml
>   <Profile id="test">
>   <Profile id="common">
>   <Profile id="desktop" extends="common">
>   <Profile id="server" extends="common">
>   <Profile id="ftp" extends="server">
>     <!--<Profile id="ftp" extends="server" 
> xmlns="http://checklists.nist.gov/xccdf/1.1" > -->
>   <Profile id="stig-rhel6-server" extends="common">

Historically we've wanted to create one large guide containing all 
rules, and have been using the following command for that. Note the 
"allrules" profile doesn't actually exist, as our understanding is that 
OpenSCAP will generate "allrules" upon receiving a non-existent profile 
name.
> $ oscap xccdf generate guide --profile allrules 
> $(OUT)/unlinked-rhel6-xccdf-guide.xml > $(OUT)/rhel6-guide.html

I'm now trying to create per-profile guides, e.g.:
> oscap xccdf generate guide --profile test 
> $(OUT)/unlinked-rhel6-xccdf-guide.xml > $(OUT)/test-guide.html
> oscap xccdf generate guide --profile stig-rhel6-server 
> $(OUT)/unlinked-rhel6-xccdf-guide.xml > 
> $(OUT)/stig-rhel6-server-guide.html

The "test" profile has 29 rules in it, with "stig-rhel6-server" having 252:
> $ grep "<select idref" ../input/profiles/test.xml | wc -l
> 29
>
> ## stig-rhel6-server extends common, adding them together
> $ grep "<select idref" ../input/profiles/stig-rhel6-server.xml | wc -l
> 51
> [shawn at rhel6 output]$ grep "<select idref" 
> ../input/profiles/common.xml | wc -l
> 201

The test-guide.html and stig-rhel6-server-guide.html end up having the 
same content as each other, even though they have different rules. 
Additionally, the test and stig-rhel6-server guides are larger 
(filesize) than the "allrules."

I double checked the 'oscap xccdf generate guide --help` output, and I 
appear to be issuing the commands correctly.... but famous last words! 
Any guidance is appreciated.
