Updating the reference anchors for NIST docs

[ajeanmahoney]

Description

For the anchor attribute of NIST docs, could periods and hyphens be used in the value instead of underscores so that the anchor value matches the DOI value and the filename?

Example of current information provided:

<reference anchor="NIST_FIPS_180_4" target="https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.180-4.pdf">
...
<seriesInfo name="DOI" value="10.6028/NIST.FIPS.180-4"/>
...

Preferred:

<reference anchor="NIST.FIPS.180-4" target="https://nvlpubs.nist.gov/nistpubs/FIPS/NIST.FIPS.180-4.pdf">
...
<seriesInfo name="DOI" value="10.6028/NIST.FIPS.180-4"/>
...
